Slack.com is a great tool for leadership collaboration. Just create a new slack subgroup for your chapter then create channels using hashtags (#) for various topic areas like #finance, #events, #membership, #sponsors, #media, #legislative, #minutes, #hupac, and more. Leadership can work seamlessly together without tracking multiple emails from leadership - all communications in one place. Documents can be easily uploaded and retained. No more losing email threads or historical information when someone leaves the board.
