As it turns out we have enough space for about 35 tables, opposed to the previously estimated 40 or 50. So far we have 31 tables already reserved, leaving only 4 to remain unclaimed. Tables are only $10 and are open to anyone involved in zines or zine making. To register just click the "Register Now" tab at the top of the page, it only takes about 5 to 10 minutes to complete. To check out the list of vendors registered as of now, check the "PGH Zinesters" tab at top. Thanks!
