Hey, sorry I wasn't around to respond to your text in the chat earlier. However, you're the first person to mention issues with connecting to the new chat. The only reason I'd imagine you'd be getting kicked is that you've or your associated IP has caused mischief on the mibbit IRC servers in the past.
The new chat is IRC based, so if you'd rather use a IRC client you can actually use one, IRC server is: irc.mibbit.com #computerhope
I'll also add this information at the bottom of the forums main page for other users who may want to connect using their preferred method instead of the script on Computer Hope.
