Quote: "TGC is an english company,so the forum is in english:this is a bit discriminatory "
A forum needs a standard language so everyone can understand one another. As it so happens most people here are English speakers, the admins all speak English and presumably TGC sells most products to English speaking countries. The lesser of two evils in the case of TGC is that the minority of non English speakers have to learn English as the forum language which suits the most users (however unfortunate that is for you lot :/ ). There will always be winners or losers in this case, and people feeling left out because they can't speak the community language are going to be inevitable.
The same would be the case if TGC was an Italian company based in Milan or somewhere. The forum would probably have a lot of Italian users, moreso than Americans perhaps, and as a result in that situation we foreigners would have to learn Italian or leave. I'm not trying to say that the language spoken somewhere online and international should always be English. It should be whatever is most suitable; so long as everyone speaks the same language so it can be better understood by a larger number of people. Discrimination does not come into the equation.

That is a bit like saying all music which is spoken in English should be sold in English speaking countries only, for being 'discriminating'. Listen to any English speaking bands?
