I've found wiredbots.com
and registered my bot there but haven't received approval for it yet. I'm not into the whole mass messaging thing, not that you were suggesting it, but still, it ain't my style. For now I have a link up in my profile and away messages that will open up an IM box to the bot itself when clicked. Its just up to the user the hit "send". I figure I made it easy enough.
I don't want the thing to get too huge, especially with all the warning fanatics out there. Just want to get some funny reactions. The screen name I use for the bot is "STFUasshat". Lovely eh? ;)
