I'd like to take this opportunity to remind the community about advertising events, including Judge Conferences, in this global forum: Please Don't. :)
Judges: Remember that you can configure JudgeApps to automatically notify you when new events, including Judge Conferences, that might interest you are created. You can review how to do that here:
http://blogs.magicjudges.org/judgeapps/your-profile-and-settings/event-notification-settings/Feel free to promote such conferences in regional forums/lists/groups, where a high percentage of judges there are likely to be interested. No disrespect to your conference, which I'm sure will be just lovely, but with over 4,000 (!!!) judges, we just need to remember that posts in this global announcement forum will be heading to the inboxes of thousands and thousands of people around the World.
Cheers - and have a great time at the conference :)
