Clarification on ticket reselling

Hi all,

I'm seeing conflicting information on whether you can resell tickets at this date. I want to ask for clarification on it. I understand BlogHer won't put new names on the badges. But if I sell my ticket and someone else shows up under my name, can they collect my badge and just put their business card in it or otherwise display their name?

Also, were we meant to get tickets in the mail this year?

Thanks!
