As you're talking about "many groupware project": do
you have a short-list
for "usable" groupware servers? I didn't know there are "many"
of them
around (yet), in fact I considered
OpenGroupware.org the first/only one
that claims a certain level of functionality that might be good enough.
As far as I know, there is also Kroupware, but I don't know much about it.
