I've added a couple things to the main conventions page - you can now see how many people are going to a convention for this year on the main section.
The costume form in your tools section has also been rearranged. There is now a "Convention History" section. If you're a Celestial member, this means you can link a costume to more than one convention. When someone looks at that costume on your page, they'll see all the conventions that costume has been worn at! Regular members are still only allowed one convention per costume - just another way of thanking our Celestial members.
Which brings me to my next point - I've thought up of a neat idea to include on the site. I'm still working out the details, but I'm really excited about it. Expect it up in a week or two - as a hint to what it is, let's just say there will be another way of earning Celestial status instead of donating...
Also, winners for the Kingdom Hearts contest will be announced tomorrow!
