Can I Log Into an Account That Was Made For These Forums A Long Time Ago, but Isn't connected to my SHiFT?

Title says it all- I had a forums account and I don’t want people to think I’m new to GBX, but every time I try to log in it won’t let me because it uses SHiFT now. Any Clue?

AFAIK the only way to use these forums is with an account that’s linked with shift. I think you’re out of luck with the old account.
