It may not need to be that hard,
if you do it weekly Member of the week.
You post the members bio that they give you a pic or 2 if they want.
and everyone who wants to can post them questions and through out the week, that member can answer the questions.
after that week you close that thread and start another one for the next member.
have it that on that section only the administrator can start the threads.
so it is only the one thread open for that week.
you can have manybe one other thread where people post there interest for being a featured member.
You can ask then for the bio and they can pm it to the admin.
You would only have to post one thread and close 1 thread per week.
But I'm not a mod, It may be a lot more difficult then that, I just don t know
