Seven Tips to Harness the Power of Twitter for Your Cause

6. Tweet it forward.
Retweet what other Twitter users say or to share a link directly. Retweeting — abbreviated as RT — means copying verbatim what someone else has already tweeted. The authors stress that you should include the person's username in the retweet, as well. When you want to share a useful link or piece of information with your followers that you found through another source or Twitter user but want to repost it in your own way, use a hat tip (h/t) or "via."

7. #Tag it!
