Today (November 13th, 2011), while playing MW3 on Xbox I noticed I was getting Double XP for most of the day. I know that you can enable it a few different ways, but I didn't do anything special this weekend. This was player XP, so like kill confirmed was giving me 100 score for each tag.
While playing, my accounts tag (not sure if thats the right name, but where the emblem, title, and more show up) had a red/orange 'XP' icon in the top right.
I didn't do anything that I can think of to enable this. And I haven't done anything special in the game (and I didn't pay for Elite). I was a beta tester for Elite though.
I couldn't find anything online stating it was a double XP weekend either.
My question is – how are other ways to get Double XP?

Signing up for CoD Elite (even the free version) grants you 2 hours worth of double XP, but they were having issues with Elite, so not everyone got it right when they signed up. The website is still down, but you can check their Twitter feed, where they're telling multiple people that they should be getting their double XP boost soon:

Chances are you signed up for the Elite website at some point, and that's where your 2 hours came from. Incidentally, when you view your playercard in the barracks, you'll not only see the gold XP icon in the upper right, but towards the bottom there's a timer that shows how much Double XP time you have remaining.
