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)

They are planning to leave us
one hour between checking whether our accounts work, and starting trades.
We still don't know whether our accounts could be claimed successfully. Maybe MtGox has not even processed all accounts. Since the bitcoin price will probably fall immediately after trades are opened, this could create a HUGE disadvantage for people whose accounts could not be activated.
Not to mention that 4 GMT sucks for a lot of people depending on the time zone.
I'd say they should give us at least 24h. I hope MagicalTux will read this thread in time.
