Steam group integration? Must have plugins?

I've created a Steam Group for my server to make it easier to handle suggestions, questions, complaints and reports but how do I actually get people to join there? I have the link in the ServerInfo and it will also come by in the AutoBroadcast so now and then, but its not clickable so people dont really bother to go there for info.

What is a good way to go about this? How do you guys do this? I'm still kinda new with managing a server but its getting more popular now so would be cool to have an active Steam Group to solve matters.

 

Offer some sort of perk for joining the steam group. I offer access to /sil and security cameras for anyone that joins the steam group and it works pretty well. You can install the plugin "SteamGroups" so that when they join your group they will automatically get added to a permissions group.
