Finally my last question; Is it also possible to make a 'upcoming expert' category to give students also a chance and involve them? There are lots of students that are not an expert yet, but they are capable enough to provide decent advice according to their knowledge about the specific thing they're studying. If the team is open to this idea, send me a personal message. I know some very interested parties to reach out to.
1. We're not creating a marketplace so we're not validating if someone is an expert or he's not. You'll be able to can go to one's website and find a link for calling him via experty there. Or you can visit youtuber's profile and you'll be able to simply call him directly.
2. We're considering refunds. Current idea is to make able to refund for example during some initial time of the call. Most likely we'll leave this up to users and 3rd party marketplaces - so they'll be able to enable that feature to improve their credibility, while some famous people will be able not to use it.
3. this is related to first question - it's a marketplace problem not the platform itself - we're not deciding if you're an expert or not. If you don't have a credibility you'll charge less to build it
