There is a little bug in comments, look at the pingbacks for examplne at: http://www.sebastian.honsa.eu/koncept-2012/ at the bottom of the page.
How can I separe comments and pingbacks styling and move pingbacks/trackbacks down a bit? Is that a problem of missing gravatar? In this case, is it possible to make a default gravatar for all pingbacks?
Thank you very much for your help.
