I don't know the answer to that. Maybe decide who you want to interview next, talk to them to make suer they are ok with it, and create the new interview thread with the original post at the top, adding your name to the bottom of the list?
Speaking of that list, I wish we could go back and see those previous interviews! Some that were held while I was gone I would love to have read.
Mocha is correct. Contact the person you choose and get their consent. Then copy and paste the opening statement and list of previous interviewees.
