if you don't want users visiting the forums/blogs use the user permissions to restrict access to them.
I know this...but if I restrict the user group from forum sections, the recent posts informer will not work for any group - it will say "Guests cannot view this". So in order to get that needed function working, I need to check the User Group for forum rights.
The problem is they are displayed under forums as viewers?
Yes, that is the mystery since 'unregistered guests' technically cannot log-in.
...yesterday when I logged in there were 9 members logged in and 6 guests ... the un-named guests were viewed in 3 different forum sections.
