Returning player - Forgotten username and pw for P99 game login

[NimbusCat]

As the title suggests, I am a returning player. I have forgotten my UN and PW. How do I go about requesting a pw reset and my username? I am able to log into these forums but I believe, if I'm not mistaken, the creds are different to log into the game. Correct?

Thoughts?

If this is not the correct place for this post, please move it to the appropriate area. Thanks!!
