Ooh, if you're open to suggestions, my number one frustration with IRC goes like this: I'm connected and happily chatting, but then my Wifi blips and I'm disconnected. There's no chat log, so I don't know what I missed. And on crappy connections, this can happen pretty frequently.
I know there are programs that'll keep you online and collect chat logs even if you disconnect, but it seems ridiculous to have to set up a server just so I can chat.
If you fix this problem, I'd happily fork over at least $10/month, maybe more.
