[Dspace-general] Hello

[Meenu Madan]

Hello All,
I just subscribed to this alias. Hope to get good info from here.
I'm working at Hampshire college as a Web Programmer and we have set up 
DSpace here to act as an archive for our final year student thesis.

Now one question I had was about authorization.
Is it necessary to make all communities public?
Secondly Can I have authorization levels based on community, like I want 
to have an Admin access over community1 and give people1, people2 only 
read access on this community1. And at later stages change there 
authorization or add more people to read access.

Thanks in advance.
