Just use our forum system in order to write messages for people to read, you can get a password protected system. but since twitter is as open as it is we feel we can trust people not to steal or lie that they didn't read someone else's content/message.  

We also have password protected pages and friend only pages for you to link to longer messages while using twitter, facebook, myspace, or youtube.
