SFI has great ways to communicate with your team, but am I missing out by not using outside resources too like email, Facebook Messenger, WhatsApp, etc.?
Yes, you need to use whatever mode of communication your team members respond to--not all respond to Team Mail or e-Cards. I personally love skype because I can talk most immediately with people, whether they're on- or off-line (they can always get my messages when they come back), and I can also talk with them voice-to-voice or even face-to-face when they're on. Remember, your goal is to keep your affiliates, PSA and CSA allike, active and participating. That's what will build your team best.
