Learn Foreign Languages

OK, so what are some of the most beautiful languages?? This question is based on personal opinion, remember Every language is beautiful.
Some language I think are very beautiful:
Mandarin
Thai
Veitnamese
French
Italian
Icelandic
Arabic
Sanskrit (I actually know Sanskrit lol)
Russian

OK so I want to make a group with people who want to learn languages. I speak hindi, Urdu, asamese and English (I also know Sanskrit but no one even speaks that now) I want to learn mandarin (seriously I love that language but I'm so confused most of the time) and Japanese (I know to read hiragana, Katakana, some basic kanji. I know phrases and greetings and some grammar rules). I want to learn German too.
I really love the mangago community...can anyone please recommend where I can create a group or if someone has created a group. I don't really use any other SNS other than printrest. But I can create a new account too.
