I have created Twitter accounts for each of the regionals, for example,
http://www.twitter.com/FIRSTSD for the San Diego Regional. Each of these accounts is being followed by Twittbot so that any reply to the account is retweeted to everyone following the account.
If you twitter a reply to the regional twitter account, it will be retweeted to everyone following the regional twitter account.
For more details of how to use the Regional Twitter accounts, and how it works, go to
