Ton Roosendaal will be hosting an 'ask me anything' session here on BlenderNation from 1500-1800 UTC. You can leave your questions in the comments below. Ton will be answering as many of them as he can.
The focus will be on project Gooseberry, but you're free to ask any other Blender related questions as well.
Tip: Vote up your favorite questions!
Update: The AMA is over. Feel free to continue the discussion!
