To collaborate with your team you need a robust communication tool that would allow team members to communicate both online and offline. I came across this cloud-based tool https://clariti.app/
which would allow you to chat with your remote team members very easily. You can also send email, share documents, assign To-Do's to your team through one single platform. It handles your information with care and it gives access anywhere and at any time. It is very efficient and easy to use.
