Good soundboard!
Well, this a good soundboard, better than the average. Complete, with lots of jokes and voices, but I still see some flaws, so I'll try to help the best I can:
Mmmh, have you got Flash 8? Why not using filters, and that cool stuff for the fonts, or the buttons? Making them look cooler would improve a lot the image of the flash. Just yellow circles...isn't enough. It's not bad, I mean, at least you can see everything properly, but can be better.
However, I liked pretty much the backgrounds you used, and marking which sentences were long, which were short, was a nice detail.
Good job!
