I commend your work and a little feedback but I may bee and am often wrong.
- I'm not sure if
AOL was actually a customer of Arsdigita at any time and World Bank
was a later day client not an early adopter.
- "OACS is independent of the RDBMS" should probably be reworded to something like "OACS is not dependent on a particular RDBMS"
- "The OpenACS 4x became the Arsdigita codebase for its ACS TCL" I'm pretty sure its the other way around that the current OACS was initially based on the ACS 4.x TCL version which was a reworking of some core kernel implementation.
These items are all from the introduction.
