Try to post it with steemit.com. You will get an error message telling you how much RC you need (or you still need, I don't remember exactly) to publish your post. Then see how much you have with Steemd and what's your estimated max.
If your needed RC is lower than the estimated max, wait until tomorrow (but don't waste your RC) and post when you have enough RC.
If your needed RC is higher than your estimated max you have these options:
- make your post shorter or with less images
- try to post when costs are lower (when activity is lower on Steem)
- don't post until the RC system stabilizes, hoping for better prices then
- power up to get more RC mana
- try to obtain a delegation to increase your RC mana (Blocktrades has an offer of 50% discounted prices for 90-day delegations, for a few days)
RE: I think HF20 has gone as expected. Now, it depends what your expectations were.
