We just took a few days out and added something automated for signup threads. It hasn't been tested on the live server yet.
If you want to try it, there's a 9pm turbo thread. No need to post IN or OUT...this new system will do that for you when you click the Join or Leave button from either the thread or the forum pages.

The join button can also be hotlinked to force signups, but that's a nasty trick to pull on someone. [img]/images/graemlins/tongue.gif[/img] (in addition to getting a bunch of non-interested players on the playerlist)
