Twitter Teams

“Most of us have become familiar with the whole hash tagging of messages in twitter. Twitter Teams works in the same way but we decided to throw in some extra spice to make it more fun. All you have to do is join the team and hash tag your tweet with the appropriate team hash tag and it will show up in the team chatter thread. If you are the captain of the team and have set up a Twitter account for your team, we’ll use it to notify all opted-in members with a summarized direct message.”
