Wow! Welcome aboard. I doubt you remember me, but I attended one of your seminars and we shook hands. Good to see you here!
BTW lots of prominent names were locked up by the devs and early adopters to keep them safe from abuse. Contact support and they might be able to get your name back to you.
Getting "jeffberwick" account should work since the recovery account that holds it, is "steem"... If he comes in contact with @dan or @ned I am confident he will get it!
