Needs to stay up for >3 consecutive weeks at least.

By @firstuserhere I mean me, the person behind the handle.

If the page is about "firstuserhere" in a context where it's me, then resolves yes. If it's some other firstuserhere, then no. If it's my given name, then yes. Or if it's a pseudonym that is mine, then yes.

Goes without saying that I'll reveal identity at a later date, for confirmation to this market.

I will bet YES because this sounds like a cool thing to have and I'd like it to happen.

If Wikipedia ceases to exist by then, resolves N/A.

Its possible for the page to be made after I am no longer alive, so resolves to NO after the close date if no wikipedia page, or to YES if yes wikipedia page, regardless of dead or alive
