Come to the Lowell Tweet-Up tomorrow at LTC. It’s free and refreshments will be served. If you’re brand new to Twitter, we’ll help you get started. You’ll create an account, upload your profile picture, do some test Tweets and learn some of the most useful tricks from experienced Twitter users who also are your friends and neighbors. If you’re already an experienced user, come and brainstorm with others about using Twitter for community building, local news sharing, everything. 10am to noon at 246 Market St. Everyone is invited.
