Hiya!
I'm the artshow manager for 2018, if you can, ensure that you are e-mailing artshow@bronycon.org and I should get it. If it's not going to artshow@bronycon.org. You can also reach out to my personal e-mail at chibishibe@bronycon.org.
Normally documentation takes a bit to go through. Right now we're going through all the final amounts and correlating it together. The next step after that would be reaching out to all artists.
overall, please do not hesitate to reach out to me via the e-mails above, I'd love to fill ya in!
