Hi everyone, thanks for stopping by. :)
I realized I didn't really explain how to use the service. All you need to do is navigate to the "upvote exchange" using the drop down menu at the top after you use Steemconnect to log in. From there you can see your balance on the right hand side, as well as the option to promote your post by "spending more upvotes" to do so. A big thing I should have mentioned is it shows random posts, so it's more for browsing and discovering content to curate :) I'll probably make a follow up post doing a more in depth walk through of using the service later. Also, keep in mind that it is still in beta. I believe it has only existed for around a month.
