can't permanently change screen name back to me

[GBinSac]

A colleague made me an admin once for a meeting, and now every time I sign on, her name pops us as my screen name. I've changed my profile settings, but it still thinks I'm her. I know I can change my name each time I'm in a meeting, but how do I re-set so that my computer recognizes me as me?

I had this same problem. I changed my name manually, but the next time I signed in, the wrong username was displayed. I thought what the heck I will just sign up again.  What I did was use the 'sign up' link, answer the questions, use my same password, etc. The next page had all of my old information already filled out.  There I was able to change my username. I hope this helps you too.

I'm having this problem. What's the 'sign up' link?
