Thanks, I think you'll be ok if it posts quickly (fingers crossed). There have been reports in the past of the SE's getting bumped up even passed the end of Oct, so you never know. Congrats!
Related question - I just barely got into E50k this October, and have the ability to select privileges now. I saw some comments in this thread that if you waited until after November 1st to select your privileges your new eupgrade credits would have a later expiry date. Does anyone know if that's the case or will they expire next Feb regardless of when I select?
