This is a fairly simple fix, but currently the Horizontal Ruler is pitch black, which looks god awful against white or dark shades of grey. (Example of it below.) Its a easy fix, but I recommend that it is changed to a shade closer to the background so its still visible, but not in direct contrast with the background. Another thing, remove it from the signature spot. (Seems to be automatic) as there is already a line between the post text and signature image.
