Slack is a messaging platform that is great for working as a team together easily. It has a web interface but also apps for Macs, Windows, Android, iOS and Windows phone. Slack provides you a space for our teams to communicate in private. This can occur directly, between two individuals, or between a group within a channel. So practically for our church, you could have our church team all on Slack and then have a channel for finance, a channel for the worship team, a channel for the youth ministry etc. It also has a some nice integrations with different services. It is also really searchable. So if someone answers a question we can make it easily available to all! Ideas, thoughts and conversations are archived to bring all up to date in communication.
