Line under the avatar?

[Black]

Hello,
I'm afraid I have to ask you one more time.
i would like to have a line under the avatar, so that the contribution ahl and halt the icons is separated. how could i get that?

Try this in extra.css:

.XenBase .messageUserBlock .extraUserInfo dl {
    border-bottom: 1px solid #000;
    padding-bottom: 2px;
    margin-bottom: 4px;
    display: block;
}

I've added padding + margin for better spacing, but you may need to increase/decrease those to your liking.
