can't seem to log in

Hi all...I need a bit of help logging in...

I have already registered and believe my user name is "bobhart"...

I cannot remember my password so clicked where it indicates "Forgotten your password?"...

I entered what I believe to be my username and email address, but I keep getting the message "Sorry, no corresponding user was found"

So I am assuming that my username is not "bobhart"...

How do I find my username? I have posted previously...

I tried to re-register using the same email, and I am told that the email already has already been registered....

When I try to post using the Name/Handle "bobhart" I am told that I cannot post as a guest using an existing "handle"...So I am assuming at this point hat "bobhart" is my handle, not my username...

Any help appreciated

Bob Hart
