Hmm, I hadn't considered that... I guess I have 3 options in mind:

• Not worry about it... and just mention at the end of each post that all comments are visible using my front end. At least anyone using Busy or Steempeak would have a logon to my front end.
• Make replying to other people's comments a gold service only. This might be too annoying or frustrating to my userbase though. I would assume initially, my userbase might be something like 95% green.
• Post green posts and/or comments from an admin account to the blockchain... with some text like "This was posted by user blah on frontend blah". My community all know each other... they can be a chatty bunch.

Some of the events and competitions have some serious venture capital behind them, so maybe I could find a sponsor. I've got a couple of ins at Nike, who I'm sure are super annoyed that all the profesh ninjas all wear New Balance on the most popular reality TV show in the US.

Just to be clear... the 50k sponsorship would go into purchasing stake in the Steem blockchain for upvotes?

You've definitely given me a lot to think about. Thanks dude!
