WARNING: Be sure you either click on the link in the upper right hand corner ("Emerald Club Fee Waived, >>Click here for more details", or enter "1721" as the source code. Otherwise, your $50 won't be waived (I almost got dinged on it).

You should get a "$50 fee waived" confirmation when you submit.

EDIT: Woot... my membership expires in 31-DEC-2037
