If you suddenly find yourself without friends on Facebook it could be they got rid of you on National UnFriend Day.Yeah that’s right, National UnFriend Day.It was started by American comedian Jimmy Kimmel.He declared it an opportunity for Facebook users to “protect the sacred nature of friendship by cutting out any friend fat on their pages occupied by people who are not truly their friends”.Of course, there is a National UnFriend Day Facebook page.On it, Mr Kimmel suggests that you delete all Facebook friends that you wouldn’t loan $50 to, invite to a birthday party or cry over if they were involved in a tragic bus accident.If you were the unpopular child on the playground then it can be ego-building to see your Facebook friend numbers creeping up and up, but after awhile it can get a bit unwieldy.You walk down the street and someone you don’t recognise asks after your cat and whether your preschooler is finally potty trained.Turns out they’re the person you see on your page as a cat eating Christmas cookies.It is hard to recognise some Facebook users without their pictures.Sometimes you have to sit and think whether someone is your Facebook friend, before you start complaining about them in your status.Sometimes our virtual world needs as much reorganising as the real world. Here are some ways to get your e-life in order.1. You might want to start off by taking stock of what you do online. What websites do you use regularly?Take a look through your browser history to evaluate. Maybe put the ones you use regularly under favourites in your toolbar, if you haven’t done so already, so you don’t have to scramble around looking for their web address.Maybe look through your favourites file to delete websites you no longer need. Unsubscribe from any old e-mail lists you no longer follow.2. Go through your list of social networking cohorts and evaluate. You might find that you value everyone, or you might find that you have a lot of dead wood, hangers-on and larkers.Lurkers are people who read all your posts but don’t actually offer anything about themselves or contribute in anyway. Some people have a rule that they only have so many Facebook friends.If they accept a Facebook request over that limit, someone else has to go. I’m not suggesting you be cruel or hostile, just that you take control of who hears about Fluffy’s little brush with death last night, and who doesn’t.You also need to check out your Facebook security settings to see who is allowed to see your posts and pictures.Social networking sites such as Facebook regularly change their set-up, and it is possible that data you once thought was private is now open for all the world to see.Google yourself, and try to look at your Facebook page that way, while not signed in. How many of your pictures are on public display?3. As an online genealogy junkie I sign up to a lot of subscription databases and journals and then forget about them until the fee rolls around again.The fee keeps rolling as long as the expiration date on your credit card is valid.It is a good idea to put the rollover date on your calendar so you can catch them before they roll around again if you want to stop the service.Some websites allow you to sign up online, but insist that you call a toll-free number in order to disconnect the service.Read the fine print carefully when you sign up for these things, and be aware that the annual fee often works out to be less than the monthly or quarterly fee.When you call some of these website call centres you get some sweet midwestern mother-of-six.She might try to give you her recipe for apple pie, but make no mistake about it, this woman is well trained in guerrilla marketing tactics.She will try her utmost to keep you signed up. If you stick to your guns about cancelling your subscription she will either offer you a better subscription rate, or she will agree to terminate your subscription.One way to get a handle on all the online subscriptions is simply to change your credit card number.That way they will have to contact you before charging you again.4. It’s a very good idea to regularly update your virus protection software. Checking to make sure you are updated should be a part of any e-cleaning regime.5. Evaluate what you are doing to back up your data. You can sign up to a service that will do it for you at regular intervals.That way if someone breaks into your house and walks off with your laptop, at least you won’t have lost the 300-page manuscript you have been working on for the last eight years.Also make sure data on your smartphone is also backed up. Some smart devices automatically back up to the cloud. For those that don’t you can buy software or services to do it for you.6. Regularly change passwords, especially on websites that use a credit card.Make sure you have good passwords that you can remember. It helps to mix numbers and letters and to make it as long as possible. Useful website: wolfram.org/writing/howto/password.html7. Some web browsers also have a ‘do not track’ option. This is a preference in your web browser that tells websites that you do not want to be tracked, which may stop some websites from collecting your web browsing data.This website will help you figure out if your browser has this option: ie.microsoft.com/testdrive/Browser/DoNotTrack/Default.html.
