Welcome to Steem! I'm always excited to see comic artists arrive, and it's great that you found your way here through Sam Seder. It's a real sign of the growing network effect, David Pakman brought him around and he's in turn inspiring others!
Steem can have quite a learning curve at the outset and no denying it's a bit rough and tumble right now, but it's a great community and so full of potential. If you have any questions please don't hesitate to ask. Can't wait to see more of your work.
