Hi,

Have you got:

• a plugin mechanism for building extension?
• if so, are your building block services documented and available from an extension ?
• is your wiki going to stay free ?

Here are how I see wikis. IMHO, a wiki is basically:

• page editing capabilities
• scripting features (providing user-friendly dynamic capabilities)
• storage (+ usual associated stuff, like security, admin, etc.).

Such features are good enough to build interesting websites (e.g. like CMS) on top of them, as far good properties like the following are provided too:

• good doc
• a friendly license
• a plugin mechanism for building extensions

So, my questions above.

Thanks.

Regards,

Dominique
