Washougal_Otaku is the panels coordinator, according to the staff list, so grab his email from the forums and try him.
If that doesn't work, his boss is Brenda, at programming@kumoricon.org
Also, if you have a hard time reaching her, Jaki in programming knows just about everything about everything in programming and is really easy to get ahold of. She is Jamiche on the forums, and uses the email chess@kumoricon.org
If that still doesn't work, don't hesitate to ask Meg, at chair@kumoricon.org
