I[1] like Wikki-like concepts and I think that it's usefull in non-formal enviroments. However, I will try to add some kind of mandatory logging so that casual users won't see any editing options in Wikki until they login. It's really necessary for site which I'm developing right now (you don't want to have comments from all over the world in-between your corporate data :-)
If I suceed in this, you will find that on [my pages].
However, first step is to include database-independent wiki. I would like wiki for [PostgreSQL]. Should I move to [PhpWiki] ?
Work is currently under way to give WikkiTikkiTavi DatabaseIndependence, with a primary goal being to make it usable under PostgreSQL.
