I don't know!!! I thought I had this all figured out, but I looked and looked and you're right, it's simply not showing. Please do me a favor and ask NING -- go to www.help.ning.com and scroll to the bottom of the page where it says "ask us" and send them the question. They will fix it up right away. This is something on their end, because it's NOT just you!
Sorry about this! I really appreciate your patience!
