Comment 2 for bug 1674097

One could also use the signature to provide additional spoken languages.

I do not see any advantage in those flags. Moreover i see some babylonian confusion if one thread contain mixed language posts. We have specific subforums for some languages, just the languages you want flags for (English, German, French). Ok Russian is missing, but i don't know users from russian.

And, in fact, we do not use any geo location apps yet. So we do not know where our users are located :-)
