[Request] Hide/move/Archive old forums

Hello!

I would like to have the option to hide, or archive forums. There is a lot of old forums on the first page. And as a beta tester there is even more... Like Concert V3 feedback. Last post a year ago, Eos 2.9.1 beta open and closed.

I know the base platform isn't ETC´s so it can be hard to make it user based how we organize the forums, but the new updated looks like you can have forum with sub forums. maybe make a "Old beta forums" that can hide all old betas?
