How should we vote or state our priorities?

[fdncred]

Good question. Any suggestions? It would be nice to allow people to upvote certain things. Maybe there's some voting site that does that?

[sophiajt]

One way to do the voting would be to let people pick their top three things, then count that. Folks could reply here if we do it that way.

[sholderbach]

As the granularity/scope of the ideas/milestones varies we may want to break the main themes out into separate tracking issues under a milestone so that we can better keep track what is relevant in that area. We than can use the one here to weigh on the focus of the general themes. Using the emojis on github with individual comments would probably get quite messy.

[fdncred]

@sholderbach I was going to split this up into issues like you did (Thanks!!!) but what do you think about adding the github emojis to allow people to vote by clicking on them? I think we just need to maybe number them and say to vote for X use the +1/thumbs up emoji, to vote for Y use the -1/thumbs down emoji. I just see 8 emojis so maybe we can only have the top 8 things to vote on. What do you think?

BTW - i added to History - ability to remove history

[sholderbach]

My suggestion would be to put a list of the eight currently most important/controversial ideas in a comment below with the emojis as labels, so we can update the top comment as an overview as needed without screwing with the past votes.

Template below:
