Well, it looks like we swamped the Sears Heroes at Home website to the point that they had to pull it down. According to the current update, "We’re sorry, registration for the Sears Heroes At Home Wish RegistrySM program is temporarily closed." (As of 1:43 am, Eastern time.) I encourage you to keep checking back in hopes that it reopens.
I will be away from my computer for several hours today, so please post in the comments if you learn something new.
