Hi,
do you have plans to make it possible to have the matrix in other languages than English?
Think of thosenot that familiar with English… 
Actually, yes we do. It has been on our mind for quite some time but we have been trying to get the functionality in that we need to make a first release.
Our biggest problem with multiple language support is actually storing all the notes and headings (of which there are hundreds) in multiple languages and then using them without making the administration interface too slow to use.
We just need to experiment a little bit to see how it goes. Anyone interested in helping should post here or email one of the Squiz staff members.
Right now Im working on a website and what kind of CMS we should use. If we choose matrix It might be intresting to get that language support and ofcourse I can help you out.
