It all sounds very comprehensive and flexible, Jandré.
I hear what your'e saying about possible OEM objections, but will sites be able to swap and compare their home-grown task lists (and what format would they need to be in)?
Yes; collaboration is good, and feedback from live data situations is always useful. A User Group (or forum) is also something nice to have (but, of course, someone has to maintain - or manage - that as well). "Two heads (or more) are better than one", and all that good stuff.
Trouble is, these days (unless I am misinformed) many of our younger brethren expect software to do all they want "straight out of the box", whilst seemingly fewer and fewer feel inclined to "muck in" themselves.
How many takers (collaborative sites) have rocked up so far, Jandré?
