I'm having an issue with broken profile pages. I can see them when I'm logged in, but they're returning 404 for everyone else. I upgraded the site to the latest Drupal (!been meaning to do that!), but it didn't fix the issue. I've run out of time for today, but I'll take another look soon.

I was super-inspired to take this stab at fixing things because Dimitri Kavouras just created his profle! Thanks Dimitri :) I'll have your profile working properly ASAP.
