Strange, because the system seems to find me, it sends me the password reset link just fine, when I give it my e-mail address, which should be the same that's used to send notifications when forum threads are updated. I can PM that e-mail address to you if that's any help, just don't want to post it where spam bots can harvest it…
Almost looks like I have a zombie account, that's visible to some parts of the software, but not to others.
