(I don't know if it's OK to revive this thread.)

CSS/readability issue:

<-- Notice that you cannot see my username of `jomarkiller`

`.post_author a:link` has a color of `#0072BC`

But so does `.post_author` 's `background-color`

This does not affect most of the folks who still post here these past couple years because `.post_author em` has a color of white which contrasts nicely with `#0072BC`
