It is not quite a custom games finder, but it is functionality that the community has been asking for. I have been having much success putting together matchmaking games and custom lobbies this past week with the new looking for group feature. We should make sure we leverage them properly to help grow the community and increase organization. Give props where they are due, I'm sure the features will get better over time as well. Also, I see 3 different clubs claiming to be the Forge Hub club, who is going to step up and organize this?
Hey there, here's the official ForgeHub Club - https://account.xbox.com/en-US/clubs/profile?clubid=3379833560198005
If you're interested, you could drop me your gamertag and I could invite you to the club for my weekly customs/testing lobby.
