That would be fine. Honestly, I'm a lot more concerned with the time involved on my end as far as hammering out the details / "rules", taking and posting pictures, documenting the progress of each persons stuff, and keeping people interested and motivated over what looks like half a year.
If the store is going to have no "official" involvement, then all of this is something I don't have to worry about.
History dictates that something like this needs someone to head it up in order to be successful. Usually, when the store doesn't fill this role, things burn hot and fast for a while, then die out.
It's a good idea and could certainly breath life into the 40k community in Abington. I would not like to see it "fail".
