Can you give me more detail? Your topic title says ‘admin’ but your post just says ‘user’. If you can tell me exactly what you want to achieve then I can probably advise.

I must be very bad at communicating. In another life, I want to rebirth as an englishman from Peterborough. That would make my life easier.

1. Ok I have a WordPress user. One among many. 
2. This user is an admin WordPress user.
3. I don’t wnat this user to appear in the forum, neither inthe forum stats, as this user is helping me the community owner with technical details, and has nothing to do with the rest of the community.

If there any way to do that?

Hide in the stats…  will this user be posting??  that is, writing forum posts?  or are you just referring to the online status stuff?  or are you referring to the list of admins or mods?

If just the online stuff, he can hide is online status in his forum profile…  the options – global options form…

If he is posting, his posts will show…  but if this is the case, you can use a filter

if the list of admins or mods, remember that wp admins are not sp admins… so he already wont show as an admin unless you make him an sp admin…  if this is the case, you can still use a filter to ‘strip’ him out…

so still trying to drill down to the goal, since different ways to skin this cat… more details always better

Can you please explain me how to filter that guy out?

Thanks a lot

not as easy as I first thought…  how are you handling display names and profiles?  that is, do you have it set up for a profile popup on user names?

which position in the admin list is this user?
