Love Slack!

I love Slack! Whether remote office or not, it's a great way to quickly send not just messages, but also notes and files. I send notes to myself, and I store files here. There's a robust ping system, so I can turn on and off pings, or select to allow some to ping my phone right away, versus others alert me but not urgently. Similarly, it's easy to level up channels, so serious, can't-miss channels send more alerts than, say, a water cooler channel that I can afford to lose. It keeps my life organized and on track!
