How can I add you as a friend? I would like to ask you some questions.

Newcomer Help:
I've just been playing in the Binance community for a few days,
1. How to send red envelopes to fans via short messages.
2. I've seen some crypto friends also form fan groups, how to create a group.
What other important features do I need to understand? What do you think are important features? I sincerely seek advice, and I kindly ask for the support of crypto friends, thank you in advance!
