Hi,
the forum is not that big and busy yet, but it certainly will be after a while and when it’s advertised.
To prevent confusions - make clear to the users that somebody is an admin or mod - I’d like to suggest that all admins and mods change their primary group, so their username appears in red or green respectively.
To do that, go to your User Control Panel -> Usergroups (to the left, in the sidebar) and select “Administrators” or “Global Moderators”. Then click on “Change default group”. After that, your username appears in the appropriate color in the forum and users see at first glance that your instructions have to be followed.
