I don't use attachments, but when you are typing a reply or new message in the "advanced" editor there's a paperclip icon to click on to manage attachments. It might be something only for paid members though, I don't know.
there are actually quite a lot of places you can find an airbrush kit, of varying prices and quality. The most obvious places to look are hobby shops, whether they're chains like Hobby Lobby and Michaels, or "mom and pop" shops. The next best place to go is hit up Google and search for "air brush" and you'll find a lot of places that sell them.
