Hi Bart,

The notes below sound all very good!
 From open source management perspective, what interests me most is how  
to improve the accessibility and maintenance of our import/export  
scripts project.

Until now, Willian has proved to be the central contact for it (like  
providing release notes). In bug tracker reports on import/export, I  
usually also assign it to him. Still, most development on this happens  
a bit hidden, behind the scenes (on the bf-python list?).

Since we release the scripts as integrated Blender functionality (and  
since it's an extremely important feature to have) I guess we should  
formalize this a bit more? Like:

- appoint Willian as 'module owner' for import/export scripts
- decide & promote which mailing list is the central communication on  
import/export issues (bugs, fixes, proposals)
- have a good documented section on our website on this
- create a 'regression testing suite' for all files we support
