I do that sometimes as well. I'll post on their profile or send a PM to see if maybe, just maybe, someone logs in and actually remembers me in regards to cringe, my profile looked like that of a myspace or "friendpages" website. i only defaulted it this past year, thank god. think i'm gonna login now just to see if I can buy the item I want on my wish list
EDIT: I bought the item on my wish list.
