Thank you for you very rapid reply! However I really like the SmallWiki and really want to use it as the "message board" for one of our interests groups.

In particular I require your login facilitiy wich let me give different kinds of users different roles (ones that can change, ones that can browse, don't let the anonymous user do anything, etc). Maybe an extension where you can restrict certain subfolders differently and making pages where some user's only could add and not delet would be nice. The former case could be used if you want a public wiki on the top level but have restricted areas for internal communication for a particular group of users. The latter situation could be useful if you for instance want to develop a lab booking system for students, were you don't want one student to delete another student's booking. Maybe some combination of these extensions could be useful if one eant to provide on-line exams. Maybe answers that only are visible to the one that submitted them and, of course, the teachers.

But suddenly we may not have Wiki anymore (but maybe something useful at all).

At the moment I am a little bit to busy to have time to look into the coding of the SmallWiki but maybe later I would have more time and, hopefully, could try out some of my suggestions myself.
