I'm pretty much regretting not keeping up with the private trackers I was a member of as certain spots started to fall apart users were sharing invites to newer sites and I didn't participate because streaming was going fine lol

Oops.

They started recruiting on RED and GGn. If you don't know either of them then indeed it's impossible.

I'm on GGn. Where do I go to look for invites?

Its in the Legendary Invites forum, so obviously you'll need to rank up to Legendary Gamer if not already.

EDIT: The thread also states you need to be a Master Gamer, and an account older than 1 year. So very tough requirements, although you can get to MG without uploading anything.
