Hi Mark,
I am really sorry for the delay of this reply. Please find my answers from your inquiries below.
1. The native ED ranking functionality is not working. We've set rankings based on points. But as users accumulate points the rank does not change. What is preventing the rankings from working?
May I know do you recently applying this ranking system on your easydiscuss system? If yes, you need to let all users to gain atleast 1 point for the rank to take effect. I've tried to post a test post using stackideas account on your site and gaining total of 4 points and my rank now has change from "new" to "contributor",

2. For some reason ED requires a login in order to view a member's profile. Is there a way to make profiles public?
I can't seems to replicate this issue in my local instance. By the way the provided FTP access seems not to be working for me. Can you re-provide the access so I can check on the code directly on your site?
