Hi,
Through mails, skype, Whatappp, wechat like this needs to be contacted for the person in remote.
For the person in the same area through phone and in person is the best choice.
Has to arrange a half early conference so that all can meet in one place and share the ideas, lessons learned, best practices will improve the business.
Webinars can be arranged for participation.
Daily Basis is the best choice so that error rectifications done immediately.
