I hate this forum I just wrotte a full answer and couldn't place the post.

There are two Russian forums, in one you have to pay to enter and in the other you have to activate Javascrypt... I haven't tried any.

I only use Omni at the moment:

People say that cryptbb is compromised, one of the owners has left the forum or leaked vendors

Session in case you feel like chatting:
