Forum Little Notepad Icon?
 

OK, dumb question but I cannot find the right setting for this. On my forum next to the name of the thread on the first post in a thread there is a little icon that looks like a sheet of notebook paper. Mouseover says "default". In every other post in each thread the icon is still there. It is not on most vB sites though. Any idea what this is and how to get rid of it? (4.0.2)
