This is from one of the members of my community site:

The problem I'm having is when I click on someone's username from a wall-post or other comment - sometimes it just takes me to my own profile, instead of the person I clicked on. If I choose the same person from somewhere else, I get to their profile OK. So it's sporadic I guess, which is always hard to debug!

And, when I click "admin" I sometimes get the message that I have no permission to do this. I was definitely logged in, and managed to get to your page (and others) via another route. (so again it's sporadic).

Also, Pam has mentioned she added a wall post, and it put it on there 4 times.

5 other people have told me the same thing, so I guess it IS a bug!
