i've been a member of PSU and the smaller G.A.P. since 2006... so i guess it's not "forever"... but i do update my account once in a while.
just yesterday, i registered another PSP... and just now, i changed my game count for a few consoles i have.
and yes, i did receive the coupon... in fact i had it a number of days before realizing what it was... too bad i got it way after i already bought Crisis Core.
