I tried to add a community-wiki answer to this week's challenge topic to start a list of questions asked during the challenge week, but it turned my answer into a comment on the question instead. (Twice before I noticed.) Why is that? Yes it's my "question", but I thought answering the "do you really want to answer your own question?" prompt appropriately would take care of that. Is there something special about community wiki?
It turns out that adding an answer along those lines that is just links gets turned into a comment as desired behavior. Not quite sure on the details of the system catching CW versus non-CW answers, but I believe this is expected. For now we'll have to use Standback's workaround to get the lists posted. Great idea on posting lists, by the way!
