Hi Derek and Sam,
thanks for taking care of this issue.
Working with children in primary schools who write lots of learning journals and want comments from their teacher and classmates, we really hoped that the new blog in 2.0 would do all this - restrict the visibility of a blog to a course and its participants or to an assignment, database, resource, etc., but allow comments. (And make a difference to a forum discussion, because it is more personal and ongoing.) But unfortunately this does not work perfectly.
Yes, I can see all the blog entries which belong to a certain course, and when the blog is on the page of a certain assignment, I can see the related posts. Fine.
But it is very easy to find links to just "Blogs". The first stop for it is the navigation block. I found the following solution: restrict the navigation to "categories and courses" and make the block invisible on site level, because from there every authenticated user can go to every blog. But this limits the navigation.
Hmmh, maybe somebody has a better idea?
