Ah, if you were an accomplished ED-er, you'd find the answer @ MJKittyMom's, but then no need to give you grief and an ED-ache, right? OK, two clues: one, go to your "Lolz." Click the very first one (assumes it actually *is* the first, no earlier deleted lols), then right-click and select "View Image." The creation date is embedded in the link; in your case, it's 2008/10/7/. Two, search your email for the "Thanks for Registering at ICHC!" message. Both methods imperfect for obvious reasons, but as good as you'll get (unless you are truly obsessed, in which case you'd know and wouldn't need to ask).
