Forum Registration Question

I got a question that maybe somebody can answer:

Hi Ben,

I must be doing something wrong, and I’m hoping you can point me in the right direction.

I’ve figured out (I think) that I need to register (separately from joining the PLC) to join the Forum, because I received an access denied message and was prompted to either log in or register.

I tried logging in with the username & password for the main site, that didn’t work, so I tried registering, but I get the message that my email is already registered.

Do you know what I’m doing wrong?
