Invite your users to vote on new requests

When a few new requests have come in since your last email, Featurevote could let you send your subscribers a short email listing them, with a link to vote on the ones they think should be built. You decide when it goes out. Featurevote tells you something like "5 new requests since your last email", you check the list, remove anything you don't want to promote, and send. It could also work on a schedule, like every two weeks, for teams that run their board in rounds. Not everyone who votes leaves an email, so a post to a Discord channel could be another way to reach people.
