Around the holidays, I like to send handwritten notes to my staff, who are also members of the communities that I manage. You can accomplish more with a handwritten note than you can accomplish in several emails or private messages, just like you can accomplish even more with a face-to-face meeting.
Unless you work at a B2B company where your community is your paying customers, you probably don’t have a mailing address for your most valued contributors. It may not be practical or appropriate to ask them for an address. But what if you could still send them a handwritten note?
