I'm managing/hosting/building the site of my church: Http://www.cgk-bol.nl
and our sistersite: http://openhof.cgk-bol.nl/mambo (Still some work in progress)
And after that more sites of our congregation (Christian Reformed Churches) became interested!
So there are a growing number of other Dutch sites:
http://www.barnabaskerk.nl/cgk_kerk_apeldoorn-centrum/
http://cgkdenhaagwest.dyndns.org/mambo (Heavily Work in Progress)
http://www.cgk-ermelo.nl/index.php
Notice that the same templates are used (they liked mine
)
