Active White-Hat Forums?

I've been digging around and found dozens of forums related to pentesting, hacking, etc but a majority of them are inactive, have few posts, or the last post was like 2 years ago.

I haven't checked the onion yet, but I figure there must be some more forums on there that are active daily. Got any suggestions?

Right now the only two active ones I found were Null-Byte and Evilzone (more or less) and I found a black hat one called V3rmllion (Which can be a mess at times).
