Hi Jason/Oxana,
Thanks for checking into it. One of the other moderators brought it to my attention. When the new member couldn't reply to a thread, they created a new thread with the answer and a link to the original thread. Not exactly what we wanted, so I cleaned up the original thread by copying the content into a reply where it was originally intended, then deleted the Answer Discussion completely.
I will follow up with the poster to make sure they can now reply and with the other moderator (Jitendra, I think).
Cheers, Mike
