Project Voodoo has two main homes :
You’re always welcome to chat on IRC on #project-voodoo , on Freenode network.
Webchat is an alternative to good old IRC clients.
Of course, XDA developers is a very good place to discuss and provide feedback, and it’s here that everything started, with this [BOUNTY] Topic.
There is of course an official discussion topic dedicated.
If you need support, try IRC first.
