" shortly after the backend is up and running we will allow customers with newly reclaimed accounts to login to Mt.Gox, and use the site as per usual, with the exception that active trading will be disabled. Users may place orders to buy or sell, but they will be queued until we enable trading, which will most likely be a couple of hours after users are able to login to Mt.Gox. "

" Users with reclaimed accounts will be able to login to Mt.Gox on Friday June 24th at 3:00 GMT (12:00 JST). Once you are logged back into the Mt.Gox site you will be able to withdraw and deposit funds as per usual. You will not be able to trade initially, but we plan to activate trading within an hour of the site being up (4:00 GMT)"

"We will relaunch the site on June 25 at 3:00 GMT. Trading will resume at 4:00 GMT (same day)."
