Ah. I should have been clearer and I should have thought a bit harder before posting.
Forget my previous sugestion, here's a second try:
For example, Lars posted this today;
openacs-4/packages/acs-templating/resources/forms - lars (7 files)
(He had committed changes to a coulpe templates)
Maybe we could place a link which pointed to https://openacs.org/cvs/openacs-4/packages/acs-templating/resources/forms/ somewhere in the message?
That way we would quickly and conveniently be able to study the actual changes.
It was just a thought.
