Ah, the problems you run into when you want to pick up a game you last played a decade ago. 
I have EU3 Complete and registered on this forum maybe 8-10 years ago, but I think I may have registered on this forum with an email address that I had 10 years ago, which has since changed. The username of the email is still the same, but it's changed from @comcast.net to @verizon.net. I've also gotten a new PC since then, so if I did register on steam (was it around 10 years ago? I think it was Gamespy back then?). I don't even remember what my old username was, just the email. If merged, I'd like to keep the current username.
Also, sending the password reset email to my old email address won't work. I tried it with my current address, but didn't get any email.
