That was a very good tip, thank you.

Now I’ve got the Community Blogs plugin installed and activated.

I also created (with admin user) a new blog. However, when I log in with another user and visit the blog and then click on the “Site Admin” link to write a post, it takes me to the backend just fine but registers me as a user to the site’s main blog. That is also where the post goes, not the blog I visited (group blog).

Any ideas? Could this be due to the fact that I have my BP installation in a directory (i.e. mydomain.com/bpinstallation) and not in the root of my domain?
