MTGOX/Coinlab transition question

[starsoccer9]

I posted many times in their thread and still havent gotten a response so I decided id post here, My question is quite simple. for us unregistered users on mtgox who do live in the us. will we need to send you IDs and such to trade and/or withdraw our money?

Also once the transition happens can I refuse to switch over and stay with mtgox?
