Just a suggestion, what if managers (who are looking for a new league) had their own topics on this forum?
Like, they could say that they are looking for a new league that meets their own personal criteria, then leagues can approach them? That way, it can help people find leagues more easily. It could be like a secondary search filter, in a way, as any manager could then find a league that is looking for players too. It could also help tackle the problem of emptier-than-usual leagues, especially for the rookie and pro leagues. What do you guys think?
