Today why I dediced to write a breif on what's app. Bcaz it's really helping me in solving major project problems. Sometimes cleint and my vendors are not available Infront of computer but we need their support all I do is Create a Whatsapp group and add my cleints and vendors. And copy all those pdf documents and snapshots of email. And discuss this in group.
Cleint felt comfortable even sitting at home they able to answer my queries since I produce them adequate Pdf documents and email snapshots.
Many projects I cleared by this method so my understanding is Whatsapp is not only a application for chatting we can solve official round table discussion we can carry out.
The voice messege and video is an added advantage of this apps.
Create a group of official and start solve your project problems.
Good luck
