Hey guys! Is there a WordPress MultiSite Demo available somewhere? I want to set that up but wanted to see what it looked like or how it worked once you have it setup.

I have already read the walk through tutorial and wanted to ask some brief questions about the wordpress multisite program.

1: If you mess up the name of a blog when you are adding it to the multisite program, can you delete it and re-add it?

2: Is all logins handled through a single login?

3: Is there a main control panel?

4: Can you link to other blogs with it?

EDIT: Just watched a much easier youtube multisite tutorial.
