Special:Badtitle/NS90:Forum:Wiki Talk/Fork date

Could someone please tell me from what date this forked TV Tropes?

(And I think that information should be on the "so you're a TV tropes refugee" page. It is very useful if you want to copy your edits from TV Tropes to know what date to start with.  Of course this is a wiki and I could put that in myself...  once someone tells me what it is, anyway.)
