I will look like the bad guy again, so be it.
It is OK for end users to communicate in their own language, this is why we provide other languages forums. Of course not everybody is fluent in English. But as far as participating to the FreeCAD project, things should be different. Contributing to the wiki is just as important as contributing to FreeCAD's code, or contributing to its packaging. And in these cases, a common language to communicate with each other and coordinate our actions is absolutely essential, and that common language is English.
I consider that to communicate in French here, where many contributors don't understand the language, is a breach of the unwritten netiquette. fylip22's Wikipedia profile mentions that he is able to communicate with an intermediate level of English. Why didn't he do so here, when he could not ignore that the whole thread and forum were in English?
One important thing to be aware of is that since the FreeCAD pool of wiki contributors is considerably smaller
than Wikipedia's, it was decided long ago that all new content had to be written in English; then translated into other languages. We simply cannot accept new original content in other languages, because we will not be able to review or translate it. I made an exception with the Creating a simple part with PartDesign
tutorial which I translated from the original French. It was a time intensive job that I would prefer not to repeat.
So provided that fylip22 understands the rules we have in place and is still willing to contribute, I will certainly be happy to welcome him in the team.
