Croatian non profit organization KNEJA ( http://kneja.hr ) has made an educational environmental web site for kids: http://pikaiprijatelji.com . Site is do-it yourself manual on sustainability in practice. Under the hood is Xoops 2.41 and Mastop Publish which is a most powerful module for Xoops at this moment (for static pages)! Site is completely on Croatian. Thank's to all Xoops developers!
