Help logging in to forum

I apologize for asking a non-dev question, but I don't know how else to get in touch without someone that can help...

I believe I registered for the ipfire forum a while back, but I am unable to log in now. When I try the "I forgot my password" option it says my email/username could not be found. When I try to register, it says "The email address you entered is not allowed to be used." The FAQ says to contact an administrator, but fails to say how to contact an administrator. Can anyone here help?

Thank you,

John
