The main issues are:
1) under the entry icon, the little usericon next to the username is partially covered, while the ones in the entry are okay.
2) right over the subject, I see a little light-grey stripe - it's almost invisible, but it bothers me. I think only the top corners are images, so that part should be the actual layout. How can I make it white as the rest of the entry? What should I look for?
3) I'd like to get of rid of the prev/next buttons between the header and the entries, and leave only the ones at the bottom of the page. Is this possible?
