Managing volunteers is hard.
On one side, you need people to do work without paying them. So you shouldn't be choosy and just be grateful to receive help.

On the other side, it is too easy for anyone to simply raise their hand offering to volunteer, but many won't actually end up volunteering/doing the work.

How to figure out who among the people who sign up will actually commit to it?

We need to vet/interview people?

So... adding more work and burden to the community organizers?

@mariatta Those are very interesting questions. I've always wondered why people express an interest in something, but then don't show up.
Did they forget?
Something happened in their life?
Did they overestimate the commitment or underestimate their available time?
Did they feel impostor syndrome?
Those are more questions, but I like to think that if we know the cause, we can try to find a solution.
@raffaellasuardini Those are all valid reasons. But sometimes people sign up to volunteer for the same reason they rsvp to a free meetup but don't show up. It's too normalized/too common, and there is little or no consequence to them.
