That was the content of that post. Make it delegated RC and there you have a rental market soon to come. This will effectively allow SMTs to enter at a much lower cost than when they would have to invest in STEEM and power up.
This sounds great to me! I'm looking forward to learning more about this as it gets developed. Hopefully Steemit Inc. has something more to tell us about these plans soon.
