Can't you just speak english?

Actually... no.
See, a good number of french-speaking people do not speak english, do not want to speak english, and some would even argue that french should be the default international language, not english. And I know what you think.
One of GUUFR's mission is to bring Umbraco to these people, and this has to be done in french. In fact, one reason for the slow adoption of Umbraco in France may very well be that everything related to Umbraco is currently published in english.
If you are an english speaker looking for Umbraco resources, you will find everything you need elsewhere on the Internet. If you do not speak french and insist on working with french people, well... some of us are quite happy to speak english (but don't tell) so feel free to contact us!
