This topic is a few days old, but thought I would comment.
I have used this software for a little over three months now and it does take a little time to get use to but it is very nicely put together and has been the best thing I have found yet to have all the great features integrated into one site.
If the (ugly) default green theme (current) annoys you like it did me, I suggest going with the "Basic Blue" theme.
It is MUCH nicer and not lime green. Just copy the contents from the basic blue theme folder into the default folder.
There is also the third default as I am sure you have seen is "alternate1" but it seems to be the same thing as basic blue when I use it on one of my test sites.
I cannot remember which one I am using now that I look at both.
If you plan on using it for work, the "Basic Blue" theme would have the more professional look.
Looks good though and just wanted to post my comments about CS. I have yet to learn how to create additional "pages" such as your IRC page.
