NLT, how do you intend to make me "go back and research the exact count" ? I don't want to do that. ;-)
What you really need is a pool for making bets on how prematurely I'll return. For example, I announced a departure lasting 1 1/2 years. So you make a wager in the pool that I'll upload to Gridcosm next Wednesday. Something like that.
The pool would apply to Gridcosm only. Uploads to Panic and comments in this forum wouldn't count.
