A forum I help administering (not the one in my profile

) is currently in a quandary - some people like the WYSIWIG editor, some hate it.
I haven't found an option where users can set their own preference anywhere, so I added a custom field to their control panel. I know I can access that field through $post['field6'], but I have problems finding where exactly the editor is called (I miss a search-by-template-title search in the admin panel

), so I have no idea where to insert it, so I can't even estimate what the problems would be once inserted.
My questions therefore:
- Which template does contain the editor code?
- Am I able to override the global editor setting in some template, or
- Is there a tutorial on the vBulletin structure language ("if" I know, but I guess I need a bit more) somewhere?
- (and while I'm at it, which mod does this forum use to have the smileys plus the help below this box? maybe I would be able to learn the required stuff from that one ^^)
Any hints would be much appreciated
