Well, I know that as a solution as well, but since they do not accept new curators, there is also a way of tipping users by sending Steem or SBD to the tipU bot with the address of the article (author) you want to give a tip. tipU will then reward that article and author with an upvote. The upvote will be worth less than the tip sent (meaning that it will always be a minus project for the one sending the tip), but it is still possible and a way to support authors you like.
