I posted a week or so about people's URLs not appearing in their profiles. It seemed this was for users who don't post often enough. Now it seems some users don't have profiles at all!
Not letting other people read profiles can be considered an anti-spam measure, but logged-in users should be able to see their own profile, otherwise it makes the forum very awkward and inconvenient to use.
The message that is returned when attempting to view a new user's profile is also incorrect. It says "User not found". It should say, "User's profile inaccessible" or something. Otherwise it suggests the user has been deleted. I came back to a post where I was helping a user earlier in the week, and I thought the user had deleted his account. I went to the trouble of e-mailing him with the solution in case he didn't read the post - simply because of the misleading 404 page.
Maybe this was an emergency measure, but it really needs to be tidied up now to make the forum more usable!
