There are no rules posted for PAX. Most expos have some sort of rules concerning toy weapons, dress modesty, behavior etc. I'm asuming that PAX will have rules too. Could you please post them (on your main PAX page would be best) so we know what they are?
Also what is the rule concerning handing out flyers? The only other expo I went to didn't allow it, will this one? I have a webcomic, and I was thinking of making cards and printing out the first few pages. Would this be ok?
