Hi! I hope you can answer a question about registering EOS? I bought some and after the termination, now have it displayed as EOS in MyEtherWallet. I thought that was it, but the instructions say:

"Don't forget to register your EOS key on or before the distribution ends on 2 June 2018"

Can you tell me what this means, how to do it, and where this key is?
Many thanks!
