Suggestions
I Suggest configuring dyno bot to prevent invite links and get the bot vortex the prevent and automute / autoban people who excessively spam to prevent the people from just spamming there server in the chat etc.
Also i think there should be a channel mainly for people looking for groups, Like have a text channel LFG where people just post that they are looking for however many people for a certain game, can help make it easier to find other people to play with.
I think that's it sorry it isn't much just thought i should suggest it :P
