Hello Cathy and welcome to chess.com, I can't seem to find your friend mhenbest either, but if you give him the following link he'll be able to see your page and be able to challenge you directly to a game from there

Hope it helps.
Well firstly Cathy, you are easy to find ... OK So problem is not with your account .
Even better Cathy, I'm not sure why mhenbest doesn't appear, but if you follow this link you can see him, and from there you can Add him as a friend and then challenge him to a game

One of the staff may be able to explain later why the accounts don't appear immediately, but for now the above link will get you under way...
I have joined specifically to play chess with a friend who has also joined.
His name is mhenbest - I can't find that he exists at all
My name is cathydepasquale - he can't find that I exist at all.
What is the problem?
