Contract or agreement signature (digital signature) attached to a project. (Tiki has the basics)
Multilingual to link together translated version of a content (in full or paragraphes/pages) and allow translation of existing content. (Tiki has more than the basics)

Each feature in Tiki has a wiki page which regroups all the bugs, requests for enhancements, etc. It is somewhat a form of wiki-based project management. You can also express your interest in a feature by adding it to your profile. You can also try out the Dynamic filter.
