New Updated!! "We have switched to a new address scheme. The addresses below will be converted into the new format by GUI software upon the first authorization. Technically it will look like this: a user enters the seed, the software generates a new address, the software sends a request (signed by the old address) to the coordinator to transfer the corresponding number of iotas to the new address."
"Don't use old addresses, those who used escrow service should hand over the new addresses to their agents once they get them generated by the GUI software."
