The SPACE organisation in Kerala has made a custom gcompris based on the old gtk+ version, and would need help to migrate to the new version.
This is a plan suggestion, feel free to comment and I'll edit it accordingly :
1-Get the translation made for the old version, and provide base for translating new version with what can be recovered from it. (note: also get the font)
2-Same for the voices.
3-Find a place and a system to host such translations that are not commonly supported
4-Help to port the customized activities in a separate branch on kde.git
5-Analyze the changes, and see what can be added as option inside the main app, and what should be possible to customize with our future administration interface.
