Oh, one small feaure request:
I notice you have some usergroup IDs hardcoded into your PHP at the moment. Not everyone's is the same, espcialy if they have been importing/exporting with impex etc.
I would prefer if the admin control panel option to not show vent server info to guests were renamed to something like "restrict server info to selected user groups" yesno option, then having a 2nd option below called something like "user group IDs that can see the server info (IP port etc)"
Then make those IDs into an array in your PHP.
I could juste edit the PHP myself to achieve the same thing, but as a default option would be nice.
Thanks again.
