For this year's project (both the Doujinshi and Calendar), the theme will be...
Now, magic can be either illusions (magicians, magic tricks) or real magic (fantasy, wizards, sorcerers). It's up to you to choose which kind. Just as long your comics are still within the theme.
As for the Calendar project, the theme is the same as the Doujin project. But remember! The characters must be ALL GIRLS! (as instructed by Mr. AKS)
As for TDD annual dinner, it will be arranged soon. Most probably after Chinese New Year.
