Another idea for a feature I had are push notifications. There could be a button saying something like "notify me when Player XY joins the server" or "notify me when anyone joins this server". Notifications could be sent by Email or any other messenger. This could maybe help to "revive" the q2 community a bit.
Or if you are using the server browser, there is a config where u can add names, and when they are online the server will be highlighted in yellow!
