Disallowing members to go stealth?

Is it possible to disallow members from chosing to stay hidden when logged in please? So ALL members are visable.

Nothing sinister here, just an annoying problem that I could do with having that option. Cheers.

Incidently I have already read through my own board options, couldn't find it (although thought I had seen it previously) and have also searched on here, but to no avail. Your help is muchly appreciated.

No can't be done. You can always just make a rule and then give them warning if they don't.

OK cheers for the help. I shall just get bossy instead.
