I unfortunately found out about this Jam only a few days ago, when I read Jack´s latest Kickstarter update on Bucket of Bolts. Stuff people have been coming up looks really exciting! Having looked into Lost & Found SRD I´d like to give it a try. Front page of the jam says that late submissions could be accepted, but I guess deadline has already been extended. So my question is, if I manage to get together something I´m proud enough of over the weekend, is it still possible to join the jam? (If not, that´s fine too, I can then finish what ever I come up with on my own schedule.)

I'm in a similar position, not gonna get finished today.  Would love to submit to the Jam but understand if no further extensions are possible.  Will still publish in due course regardless.
