Did you ever needed group chat in ICQ? I did. Thanks to great Net::OSCAR it was a joy to write (but, it took me quite some time to find Net::OSCAR in the first place).
On unrelated note, I started forbidding comments on my blog. Sorry about that, but I don't have time to change blogging software now, and amount of junk that I receive in comments is several times higher than real comments. So, if you have a comment, feel free to send me e-mail at dpavlin(at)rot13(dot)org.
