In general I prefer to be contacted publicly rather than privately.
In a chatroom
If you have questions related to Open Humans, I’d like to encourage you to join the Open Humans Community Slack group.
Use this to get an immediate invite: https://openhumans-slackin.herokuapp.com
You can also contact me on Twitter at: @madprime
If you prefer to be private, you can reach me at my Open Humans email, which combines my first name with the openhumans.org domain.
Finally – and at the other extreme – my Keybase account can be used for encrypted correspondence and file-sharing: https://keybase.io/madprime
