Web page designer McCal Roberts is offering copies of an instructional DVD on social media for free, providing takers give a seasonal charity donation of any amount to the Salvation Army.“The DVD includes video instructions on how you can set up a Facebook page and a Twitter account, and how you can get the most from social media for social and business usage,” Mr Roberts said.“As it’s Christmas time and a lot of people are struggling, as I read in the paper the other day in the story about the Salvation Army, I thought it would be nice to give away the DVD in exchange for a charity donation.”Mr Roberts hopes that those who use the DVD will seek out more of the instructional material produced by his company Mac10 Inc.He said the DVD would be available at the Esso 24-hour gas station on Par-la-Ville Road, Mr Chicken, Arabian Chicken and Shine’s House of Music.For more information, visit the Mac10 website at www.mac10inc.com
