Yeah.... The group would have 1000+ members already but unfortunately Steam (Valve) was having some issue with bots starting steam groups and sending out mass invites. So in order to invite someone to a group you have to be their steam friend now, which is ridiculous. It makes all the sense in the world to invite people in your server to your steam group or just players in the server with you to your steam group but unfortunately steam disagrees now. Also... steam's "Players" menus are horridly bugged and don't show a lot of recent players even if they did allow you to invite them to your steam groups. Steam is a disaster.
