I've been using hotmail since I created my SE ID, I've recieved all correspondence so far (even my Alpha and Beta Phase 2 extra key that I never used).

If it is hotmail, perhaps its just this time? I can't say for certain; I am checking everyday to see if I get a PS3 beta code, but I dunno if I just haven't been chosen or if the email was filtered (yes I check spam folders and all that)
