Looking for ideas to keep the DC in touch with their friends. They don't have phones so wondered if anyone has done similar and can share ideas that work in different platforms. A few of their mates have iPhones or iPads so I'm thinking iMessage but I've never actually used it. The Kindles are a bit overloaded and slow so unlikely to set up on this but could do it on the laptop for them. Slack maybe? Any ideas welcome. Thanks!
