Yep. The way we do it is the admin (I'm the only one) has basically full control over every aspect of the forum. Moderators have a few restrictions, such as no permission to hard delete posts, create custom warnings (now), etc.
this is really painful.
supposing one does edit out the custom field from the template, the result is that none of the predefined warnings have a selected radio, which then leaves the form in some sort of phantom state that allows the number of infractions to be 'cosmetically' altered until a radio is selected.
we really need the ability to reel in mod permissions with the warning system.
pick a warning, pick whether to give the predefined points or not, and submit. no personal messages, no arbitrary points, no custom warning types or text. please. this carte blanche moderation only creates problems.
