You can configure your Twitterbot to retweet posts from your bot's Twitter page in its Admin Console.
A Twitterbot can retweet posts from its friends, or from a tweet search.
You can add a single, or set of retweet keywords. Any post from your bot's friends, or search results that contains all of the keywords, or hashtags, will be retweeted. The keywords must be separated by a space, and each keyword set must be separated by a new line.
