I'm looking for a serious group too. It's very difficult.

I think to join english learning in whatsapl group is more useless.. Because most of group is not provide an admin to rule or give an material for learn. I think its more efficient and effective to have a personal chat and start a video or audio call and try to solve problem together

Yeah, let to create group

Yeah, but sometimes great information are shared on WhatsApp groups.
I had one, but I lost my phone number.

Yeah, you dan add my phone number
