Flash forum.

And how many question about Flash do people ask daily and weekly?
Not very many at all. The problem is that we don't have any category that fits that. It is far from a scripting language so the posters will have little help in that category.

Take the AJAX (http://www.dev-archive.com/forum/forumdisplay.php?f=88) forum for example. Brad founded that forum February 9th of this year. There have been 20 posts. Since AJAX is a mix of client-side and server-side, it did not apply to any forum. Brad added a new one to minimize confusion.

I think that Flash should be added for the same reason even if only 20 posts make it there in 4.5 months.
