It seems that MtGox has updated their website by providing a login option, so that users can check their wallet balance in the service to see what coins and money they are having in MtGox. There is also the text below that describes what is the purpose of the login option:

Important announcement to all users confirming their account
This balance confirmation service is provided on this site only for the convenience of all users.
Please be aware that confirming the balance on this site does not constitute a filing of rehabilitation claims under the civil rehabilitation procedure and note that the balance amounts shown on this site should also not be considered an acknowledgment by MtGox Co., Ltd. of the amount of any rehabilitation claims of users.
Rehabilitation claims under a civil rehabilitation procedure become confirmed from a filing which is followed by an investigation procedure. The method for filing claims will be published on this site as soon as we will be in situation to announce it.

We have logged in to check if the website does indeed show the correct balances from before going offline and we could see what we’ve had in our account listed correctly. Just a few Bitcoin cents that were there for the sake of testing some automated trading solutions with MtGox support, otherwise we would not have any BTC there.
