My b2evolution Version: 2.4.2

Hello Everyone.

I'm new user and a first time poster. For various reason, I am trying B2Evo and have been trying to setup a multi-user-multi-blog (each user will have one blog) kind of environment. Inspite of reading FAQs, Docs about stub files & blog settings and searching for relavant threads, I am still kind of confused about my requirement which I am listing below. Bit lengthy post, Sorry.

[u]Basic info first[/u]: I want to setup the mainblog or parent blog, whatever is the relavant term, in the root of the domain. Through the admin I want to create more blogs assigned to my friends with restricted permissions. This means I will be the Super Admin of all the blogs. (I know its common sense, but I'm writing this so that it may help others who are in a similar situation as mine)

1. Can I 'create a new blog' from the admin area, in such a way that the URL looks something like 'http://xyz.com/nutcasesblog' or 'http://xyz.com/crazygalsblog'. If yes, will anyone care to explain?

[The solutions I could think of...

=> Create separate folders in the root for each blog & have a independent installation. This will be too much to maintain & rejected outrightly.

=> Single main installation. Create the child blogs. Create folders '/crazygalsblog', '/nutcasesblog' & so on in the web root and have an index.html inside each folder which redirects to relavant blog ID or blogX.php. ]

2. If it is possible, how will the media be stored physically? Can I store them separately too? For e.g all images, videos, sound files related to 'crazygalsblog' are to be stored in the folder '/crazygalsblog'. Reason for this is, IF NEEDED I can create separate FTP accounts for each user to access their media.

3. Is 'http://crazygalsblog.xyz.com/' same as Case 1 ??

Thanks in advance.
Cheers!!
