So lets be clear here, this isn't General Chat. You're held to a higher quality of posting if you want to retain access to this place.
Currently you can apply to the group by going to Settings > Permission Groups. It should be clear which one you should be applying for. From there, I'll be looking at your posting history and considering whether it's worth letting you in. If you've got an issue with that well...sorry, but that's the way it is for the moment. I'll also be moderating here in particular, so send me a PM if you have any issues with posts in this subsection.
Depressing stuff aside, hopefully we'll actually be able to have some decent debates without all of the shitposting. I know the gun control debate tanked in General, and there were several things that contributed to both those threads demises. If all goes according to plan we shouldn't run into any sort of issues here.
