It's the thread where we say "hello" and "we'll take your soul" to new mods. You apparently started it on February 4th, 2005, 04:46 PM, with the message:
"Since the welcome thread was started when I was modded, then got deleted when we cleared out all the fluff... I think we should start it up again.
Anyways, welcome to our newest mod... KELSEY! I'm sure LT'll be very happy about that ^_~ I've always thought you'd be very suitable there... and... stuff... HOORAY!!! "
