If a person can appreciate the show enough to donate money for their "hobby". Then they can at least appreciate the fan enough to throw them some stickers like they advertise on their dedicated "Sticker" site http://www.hak5.org/stickers. here it has a few Q's & A's and one of which says:
Q:Do I get a confirmation number or anything?
Nope. Though you do get a nice personally written email from a cast member. If you don’t receive your stickers within 10 days give us an email.
I have replied to that with an email, along with talking to a couple cast members in IRC, then on the thread and was never answered back. With that said, should i expect them sometime before next May when they take $20 more dollars as i singed up for $20/year?
