We use a program called Zoom to host our meetings. It's like Skype but a more secure and private group conferencing software. It does work via video chat so you and the other group members log on with your webcam so you can see and communicate with each other (if needed you are able to access the meeting by telephone). Additionally, there is a private message board just for your group to connect throughout the week. This is accessible via anonymous text message (a.k.a. you don't have to share your number with the group), app or desktop.
