Regarding the remark added in version 12 regarding the Profiles team, I don't think this is helpful. I agree it would be particularly logical that this page be maintained by the Profiles team, but it's not a bad thing if others get involved.
The following is a list of keywords that should serve as hubs for navigation within the Tiki development and should correspond to documentation keywords.
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.
