[Koha] need a connector to wiki from main page

I just tried to get back to the great list of RFCs that are on the wiki sub-domain and was unable to get there from koha-community.org. Shouldn't there be a link to the wiki stuff? And how does one decide what goes on the wiki versus what goes on the main domain? There seems to be a lot of overlap in some categories (documentation, get involved/participation, Download Koha/Koha Versions).... I'm working on a revamp of the evergreen-ils.org site and we are struggling with these same issues.
