People have started to send "real life" info : https://bitcointalk.org/index.php?topic=2000113.msg20603056#msg20603056 but I have not found a clear description of what that is? So I sent a scan of my passport yesterday to email@example.com, but had no reply.
But today there is more: a new wallet with a change of address generation process, came out, for security reasons, Iota transitions from addresses generated with CURL to addresses generated with KERL.
For people with IOTA, the situation is clear (read the post of the link above), follow step by step the instructions.
But for people like us, waiting for a major payment on a previous CURL address, I do not know what is the best to do...
Nothing if the security issue is not too urgent and we can transition once our claims will be proceed... or send firstname.lastname@example.org a KERL address with usefull info by email... this would be safer but may increase his difficulty to collect, store, verify manual claim infos.
In a normal situation, I would say, let's wait for instructions.. unfornately, nothing normal here. I hope someone with intact relationships will ask and report.
On a positive note, CFB suggested that our time is approaching : https://bitcointalk.org/index.php?topic=2000113.msg20697286#msg20697286
