For those still finding it difficult to post, it's probably because of your low RC value. I advice you go to www.blocktrades.us to exchange some steem for steempower delegation. You need around 130 steempower delegation, and that will cost around 8 steem. You also get this steempower delegation for a whole 90days.
I hope this helps us effectively participate in Hive account@originalworks contest.
All the best.
