Password for this forum?

Didn't work for me either last night or today.

I've had this problem for several weeks, now running FF 6.0.2, although I doubt the FF version has anything to do with the problem. I sent the following e-mail to [email protected] on 9/20, and have so far received no reply:

I've been having login problems on Mozilla sites lately, apparently because I can't remember my username. Since I can't remember my username, I can't request a password reset.

I've tried the usernames in Firefox's Saved Passwords file, but of course they don't work. I can't reregister because my email address is "already in use", undoubtedly by me. One of the Firefox sites eventually gets to where they claim to send me account information, but that never shows up, either in my Thunderbird client, or in Verizon's files -- either mail or junk. I've tried this many times with the same result,

Is there any way to simply delete my e-mail account from all of Mozilla's websites, forums, etc., and let me start over?

I've established a new account using a new e-mail address, so I can start using the forums again, but I would like to get back to using my "real" e-mail if possible.

Interestingly, when I post anonymously and am asked for an e-mail to confirm my subscription to a forum, I use my "real" e-mail, and receive the confirmation request from [email protected] OK. It's just the password-reset e-mails that aren't working.

I have asked for 2 confirmations of what my username and password is, but they never show up. Neither in my junk box or regular email. I can get the email telling me how to change my password, but there is absolutely NO way one can easily find out what your username is if you have forgotten it. All the damn "help" and "contact us" links bring me right back to the "support" forum where it only answers questions it has posed. God forbid you have a new question, like "WHAT IS MY ACCOUNT INFORMATION??" is there any actual customer service for Firefox?

Sorry, if you don't remember your forum username, you can't get your password emailed to you or reset your password.
