I am interested in the Blog tool for Concrete but the describtion and vidoes are not very explaning in how it is actually is working.

Will the add blog content be on a normal site that you can access in the standard layout of the main site or (as it seems to be) needs to be done through the Dashboard?

Will the users be able to add pictures that are seperated in there own sets so they only can see own pictures and by this many fewer.

What I am looking for is a way to have about 12 main writers in a shared blog that should be devided in maybe 4 or 6 catagories. I cannot see if this is possible.
Is there a demo of the blog tool that I can get a look at before I buy anything?

Thanks
Jens Peter
