Need some info, first timer Options

[Altf4]

Less than a week away, can't wait.
not too sure how the information sources out. This site is my only contact

Been told we'll be paying entry fee on the day, is the sign up list official? ie. checking names or is it just a measure of potential attendance.

How will the seating be arrange? first come first serve or pre-assigned. If pre-assign where do i sign up.

Say i wanna share my homemade porn, what prog would i use to exchange it. DC++?
