Well, as far as i can tell, *my* private information has remained private, when i made the calls to report my CC's comermised, i reviewed the statements with the card companies, saw that no fraudulent charges were made, closed the cards, and have had new ones issued. I've already changed my passwords to nearly everything i'd log into, well, everything of merit, i haven't bothered to change my Escapist login or anything like that... losing my forum ID wouldn't be all that big a deal to me... heh.
I've already contacted my Gym and will pay this month's fee's today with a check, and update my payment info when my new discover card shows up, I canceled my city of hero account outright because, well, i haven't played it in a month or 2, and have no desire too, and that basically leaves me with updating my freecreditreport.com account with new payment info... they tend to bill me on the 19th of each month, so my coverage won't laps. And i'm switching to game cards for my XBL account and, if i ever even consider a PSN purches, it'll be a game card, so... out side of a few minor inconveniences, most of which i've already resolved, and a week without my CC's, which may actually SAVE me money... i can't see see were i'd have any grounds to join a class action suit. *shrug*
TLDR version, nope. I was hardly effected at all...
