Been annoyed with Doodle's more and more aggressive "pay us" stance recently, so went searching for some sort of alternative. I'm #polyamorous, working in a community of polyamorous people. Scheduling is a PAIN without polls, and also, I don't need to schedule so many meetings that it's worth paying what Doodle wants.
I'm pleased to report that Framadate (https://framadate.org/abc/en/) appears to be an awesome and free alternative. That, amusingly, I'm now going to go give money to.
