I know how to make one, so don't worry...

I was just wondering what a flash website should have? (apart from content)

-Preloader?
-A lot of animation?
-Animation?
-Tool tips?
-Interactive Navigation?
-Good Graphics?
-Register/Login?
And what else?

I am making a flash website for a project, to present my tutorials for my community service project. The only problem is, I'm not very creative with flash, I need some good ideas!
thanks!
-Jasper :D

Also, what would be a good size for my website?

550 * 500
500 * 400
600* 500
other?

Even if you don't know flash, ideas are welcome. Everyone can be creative :) (except me... ;D)

if you lack creativity, just look around the web for something you like and create something similar, without infringing on their copyright.
One flash site I happened to bookmark once under the title "hele goeie Flash site" is http://tararao.com/robwell/rw/index.htm for example, but something like that may not be suitable for what you're making. Just browse the web a bit and borrow some ideas here and there.
As for size, Flash animations are usually smaller, but unless it's graphic-intense, you can make it as big as you want.

http://coolhomepages.com/ has a bunch of cool flash sites you could look at. I don't know what to add, all those ideas are pretty good. A preloader with a good intro is pretty important. Hope that site helps. Or search for "Flash Sites" on google or something, should help give you some ideas. :)

Make sure to give options to those who have slow connections/dont have flash/dont like flash etc
so if you are useing a flash intro, be sure to have a 'skip it' link, if you are useing a preloader be sure to have a 'skip it' link and if you are useing flash for navigation be sure to have a non flash option too.

well, no need for a skip intro. I'm going to make it for a project. I wrote a few tutorials for flash and photoshop. So I wanna show them what I'm gonna learn them.
