I hope someone could make an add-on that has the same functionality like doodle.com I'm probably not able to fund the whole add-on myself. But I don't mind paying for it. And then the developer can release it to the community for a fair price. I could just use Doodle, but users have to register to make a new doodle. And that's why the add-on would be useful. The main reason for this is when people trying to meet each other now they just post when they are available. But it's a mess and it is impossible to find out when everyone is available. Doodle functionality would make things much easier.
