Setting STS document folders to be read only?

[John Rutledge]

Hi, - in SharePoint Team Services, there is a setting called Edit Access
under the General Settings in Announcements, Contacts, Events, Links, and
Deadlines. Setting this to "none" effectively would make those lists Read
Only. But Documents and Issues don't have the same Edit Access option.

Is there some way to accomplish this same setting for Documents and Issues?

thanks in advance,
