IMPORTANT: As of 1 September 2011, I recommend that you download the fork of Rash here: https://github.com/paxed/rash-qdb-fork . Rash is a clone of the website bash.org. It was a project of mine in high school, and is no longer maintained.
The RSS-IM Gateway allows you to let visitors read your RSS feed through an Instant Messgaing client, using AIM, MSN, ICQ, YIM, or Jabber. A Perl application, it is very easy to set up and can easily handle the hundreds of users you can expect to use it.
