In our team there are 4 remote guys. We communicate in Slack, share Google Docs when needed, track tasks in JIRA, collaborate on the product design in RealtimeBoard app, conduct daily meetings via Skype. To support the team spirit we organized several AMAs within the team via Skype. There was no restriction on the questions, so we also learned some facts about employees private life (f.ex. when they have shown their pets).
