[Staffslug] Twitter n stuff

Hello all! I'm trying to get Twitter up and running on the site and I've tried a couple of widgets and they don't appear to be playing ball. (there is a very, very good chance that I'm not setting them up right!) I was wondering if anyone has any good recommendations for a good widget for wordpress to get us twittering :o) Also, anyone know of a good web-based java irc client we can have on the site to enable people to IRC us?
