I've successfully linked my Steam account to my new forum account, but I'm not sure how to link my other account information.

I have a PG login. Do I link that with this?

I also have a Kickstarter supporter dealie. How do I link that to my PG game account, this forum account, and Steam? I'm a little concerned something is going to get lost in the shuffle or not connected right and I won't be able to play when it all gets turned on.
