Competition and standards
HERE is a very cool one! That is free and I think could be integrated with Tiki easily by some clever coder in the community.
Here I would like to see some "editorial" content. How do our features compare to others?
CVS Doc section
This is where new features being developed and only in CVS are documented. When the CVS becomes RC/official release, the info in the CVS docs is transferred to update the official docs (FeatureXDoc).
Where ideas can be exchanged, debated, etc. Interested people can subscribe to the wiki page and/or to these forums as they would a mailing list.
