We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
I'm not too sure as I don't keep track, but I would guess it was the first few years when it was all new and fresh. I would say it was about 30,000 in the first year of my 360 which was 07/08. This year I roughly earned 11-12,000 gamerscore.
