In the live chess window there is a chat tab.  One of the options is française.  Française is a French woman, implying it should be for women only.  If you mean the language, it should be français (no E).

It depends. Salle (French for room) is feminine. In that case, I think française is correct. However, there may be more than one word for chat room. E.g. "Salon de discussion" is masculine.

Another error is that 日本 should be 日本語.

No, a French room would be La salle de français.  If there is another word for chatroom, it'll be chatroom de français.  Je pense.

If it's feminine, then all words describing it are also feminine. So La Salle français is wrong. It should be française.

According to Wikipedia, the French for chat room is Salon de discussion, which is masculine.

With this it'll use the possessive form of de, which will use the gender of the noun following de.  The language is masculin.

i think it's about time we all come to terms with the fact that the french have about the coolest flag ever.

What about the language?

well i can't deny its influence on my own native language.  i quite like it.  german + french = ang-leesh

What type of an englishman likes the French flag (or anything)...

i'll pretend you didn't ask this question.

How about "where we keep the Frenchies"?

La centre de snobberie?

I reject french fries and substitute freedom fries!
