Is TikiWiki suitable for a collaboration network with workspaces
I'm considering TikiWiki for a international collaboration network. It would consists of one Tiki website that allows users to join workspaces and easily add content to the workspace (pages, tasks, media, chat). The workspaces are similar to what you would expect in project team space, but this network means the structure is more flat and the collaboration between teams is more self-organizing. Users need to be able to create workspaces by themselves, and become admin for that workspace to accept memberships of that workspace.
I see in the Tikiwiki docs an explanation of how to work with workspaces (categories and groups etc) which I tried out, but to me it seems very non-intuitive for users to work with. Tiki has clearly not prioritized the collaboration features in the sense that they can be used easily out of the box. For example, I managed to set up a workspace as admin, but still don't see how to automatically add create content to that workspace with one click, in a workspace menu that allows for that.
Anyway, I just want to be sure I"m not wasting time using TikiWiki for something that it may not be specifically built for. Feedback about this is much appreciated, thanks!
