"To recommend a post, go to the comments section of the most recent Steemplus post and ..."
This is a smart way to go about it on your part, to reduce or eliminate multiple submissions of the same link. This could also prevent "dividing the bounty" amongst those who DO submit the same article, simply on a "who suggested it first" fair's fair basis.
"We will only be featuring content that was posted under 24 hours ago..."
This might need some definition as this plays out (I could be wrong too)... Les than 24 hours from the exact time of submission, or 8pm EST, for example? Great project, hope it takes off!
