Sort:  

You can see who upvotes what post of yours (back for a week anyway) and how much
Your posts have garnered, for the week.
At the end of the week whatever value a post has comes back to you.

Very useful, but if I understand it correctly, my 100% upvote is worth 0.00 anyway...

That depends on many things, much of it I don't understand
(yet) Here is what mine looks like (remember, I keep mine normally turned down to around 30%= 1¢)

Oh ok. I looked up how to adjust the percentage and saw you're able to get a slider bar when you reach enough sp. Right now the only other way I know how is to go into my esteem app or the site you shared everytime I want to adjust it. I wish I could keep it at 100% for posts and maybe 30% for comments instead of having to change it back and forth...thanks for the upvote!!! :)

Thanks, I'll check it out!!
