I recently joined here, & it was letting me post answers in Q&A, but the next time I tried to log in, I was unable to post in Q&A or log into that section of the site, so I created another account for the Q&A aection, but the same thing happened with that account. I never received a registration activation e-mail for either of my Q&A accounts, & it doesn't send me a password reset e-mail, either. (I have 2 e-mail addresses already, so I didn't have to create a new e-mail address.) Does anyone have the same problem or know what to do about it?
