HI JJ, and welcome to Tikiwiki community!
TikiProject was developed by that guy Gary said, with the help of others, afaik, but at the end, it was finished by that guy and he was only selling the code, not contributed for free to tikiwiki community, unluckily... :-/
On the other hand, Workspaces for project management can be used within any 1.9.x version of Tikiwiki for production (or 1.10), through installing AulaWiki Mod!
It's being used for production in some sites, such as
- http://edu.tikiwiki.org (example - Tiki 1.9.7cvs)
- http://gclub.ub.es/carpetiki/ (private, used for education at university - Tiki 1.10cvs)
- http://moviments.net/cursos (example - Tiki 1.9.7)
See the English documentation (made using Workspaces on 1.9.x at:
Hope this helps...
