Hello!
I have some categories/boards that are only for selected users. However, when just a normal user takes a look at the stats, they show the total number of categories and boards even for a user that doesn't have access to all of them. So a user sees at the stats that there are 15 boards but he can only find 9, so he starts sending these "WTF?" PMs to me ;). Is this a feature or a bug?
Edit: I'm using SMF 1.0.5
This is a feature. It shows all the forums stats. On that area. If you take a look here there are over 50 boards but you can only see about 30 of them.
More like 48/73 :p
If you really are getting too many PMs (I've never gotten any about this that I can think of...), just make a sticky explaining why some boards are hidden.
