I recently came across a site that uses OpenACS so I followed a link to the OpenACS site to learn more. It's difficult! I learn, for instance from http://openacs.org/faq/one-faq?faq_id=43840 and http://openacs.org/about/what-is-openacs, that OpenACS is a toolkit etc. but beyond the DBMS and app server components, the tool content of the tool kit is buried so deep that I haven't found it.
Functionally, what tools does OpenACS offer?
For instance, is the software behind this forum part of OpenACS toolkit?
