So the purpose of this chart is to explain Giveth to newcomers in the space and help w onboarding? And you’re asking us to put suggested role description titles?
I think the chart should be re-organized… people aren’t really in the right places… like Magenta, Ben, Bryan, Kris, Tommy, Cameron… they’re not regularly contributing to Giveth… if we want to include past contributors who had an impact… or occasional contributors… maybe we can add other sections… then we should also include James, Merlin and even others… 
or we could simplify it and create some kind of date bracket… include people active within certain dates… or who were active for some period of time… and have those parameters written on the chart.
If we’re going to be talking about people who are actively involved… I should be in communications. Hannah should be in governance. Ashley should be in community… Mitch should be in communications as well… Ashley, Mitch and I should be in platform… WIlly should be part of governance ?
Platform should have multiple groupings too… Development, Design, Testing… or we could do TRACE, giveth.io GIVeconomy…
I think perhaps the best way forward is to create a better structure and then ask the individuals to place themselves in one or multiple groups.
