Free conf Call? 回複：既然說到周會, 就議論幾句

I use Skype but I need to input some money to make the call.

How can we do the free conference call? maybe I missed something. Can you help to make it clear? How to join the conference in Skype? I only see Laotu's ID on skype but can't join unless I make the phone call.

I was really confused last night.

Hope to learn more.

Thanks!
