Ive had this account for a very long time, but when I want to post something to the site, to help identify a car, it doesnt recognize my user name.

Please help the guy asking about Ben Folds "Brick" video. I cannot post a response because it doesnt recognize my name.

Tell him I think its a '63 Ford Falcon. And let me kbnow how to directly post to the "unidentified" pics

Registration for the site and the forum are entirely separate. You need to register for the site if you haven't already done so:

That site says there is already an account for my email address.It won't tell me what that nickname/password is.

I got it....i can post now...cool
