@phil, was your comment about the lack of project management functionality directed at the "project management" bullet in my reply to the OP? My intention is to use existing functionality only as a baseline for what can be achieved without adding any new features.
You may recall our discussing this last fall
on the forum, and
on the web-erp-users mail list. I'll "re-open" our old forum thread so we can discuss this further without hijacking this thread (I need to post an updated URL for my draft tutorial anyway).
