Make sure when you post that form on the thread, to have a demo of your voice talents uploaded somewhere on some website for people to get to.
Also, to really get roles, you're going to have to be active. Flash animators usually don't go for you and scout you out unless you're really talented. You're going to have to tackle them down yourself and make sure they notice you (give them your contact details, etc.) There is a chance that a flash animator can see you on the VAC Roster and take a look at your demo and think they could use you for their movie, but not guaranteed. That is why I recommend staying active.
