looking for active guild

Hey everyone, so I got really excited for this league reset, but when no one in my 100+ member guild wanted to team up to run through the campaign it really killed my buzz. This whole guild was just playing solo and then linking items in the guild chat (flexing i guess?).
So I'm wondering if there are any active guilds here that are looking for members?
Or what's the best way to find another guild?

Are there any chats or forum subs that are for guilds?
