I think using Skype or WeChat is a good way to enhance group member’s communication. I always use WeChat send word message, voiced message to my friends and family members, and even video chat with them. It is very convenient but in this time, we decide use another one, WhatsApp, keep contact with each other because it is a worldwide chat software. It is very easy to create a new account because it can connect our mobile phones and e-mail addresses. So, David create a group, and then, he invite Zoey and me join in this group. I feel like that WhatsApp is very good for business. I think WeChat is a little bit for entertainment or fun.
I find that WhatsApp has a weakness which is that it doesn’t have video chat function but I think it is enough for group communications. We use simple but clear words and useful images which can enhance our working efficiency.
