I'm the core developer of TikiMaps, I fixed other things when I find them and when I have time...
I have built this site: http://map.sopac.org
I have also built the following TikiMaps sites:
http://www.lands.gov.to/
http://map.mrd.gov.fj/
and integrating Maps as a feature inside tikiwiki.
I'm working on The Internet Force as a site to discuss the Internet.
