Gizzy.. I just installed your V0.2 and pJIRC for the first time on my site (with UBB.t 7.02). Works great. There is an inherent bug however that should be addressed. It has to do with working around the iirc requirement dateing back decades that the first character in a user name on IRC may not be a number. So a Message Board user with the name 123Sam will get an "Invalid User Name" error. Can you modify the script to sense the first character of the screen name (I'm assuming that's the field you're using.. at least I hope so), and if numeric, to prepend the user name with some character or string defined by the admin? That would be great. This same problem existed on the old jIRC hack for UBB.c. It may have been corrected in later versions.
I've installed it on my site.. but it's only visisble to members. Feel free to sign up Gizzy.
Thanks!
