So I know my friends love going to PAX West, and I would love to bring a bunch of these with me the next time I'm able to go as a fun way to help promote other indie devs as well as my own games.

Does submitting to this jam mean someone can print the submissions out to hand them out? Or should permission be retrieved on an individual basis?

I think this should be permission on an individual basis.  When I was making the map of entries, some people were OK with sharing/posting while others weren't (or I couldn't contact them).  I'm hoping to print for taking to conventions or upload a deck to a virtual tabletop of the ones that give permission but won't have capacity for a little bit since there's some other stuff going on right now - if you want to work on it now, that would be AWESOME and I will do what I can to support (and PLEASE I want to share copies with people)!
