When posting a message, the user can select a category for his message. With the current software the category defaults to the first one in the category list (normally something like "General"). However, some users are quite "lazy" and don't bother about the category selector, so some messages appear erroneously in the "General" category. Is there a way to force the user to select a category before he can post? For instance leave the first entry in the category drop-down empty (or enter the text "Please select..."), and allow a posting only when another entry is selected.
