1. How can I get the value of the post number of the first post and last post on the page?
   
2. Get the username to show up in a hover action over a button in a post? I'd like someone to hover over "Thank the user" button, and instead of Thank the user, I want to display "Thank fred50"
   
3. How can I change the button images of certain buttons in postbit when user clicks on it?
   

{$post['username']}
