There is no reason there are hidden. I think the problem I had was that the dashed border would appear even where there was no poster and I got overzealous or something???

I'm trying to see if removing this code would cause problems... Maybe with padding but I'm not sure... Let me check.

Ok so I think replacing:

    .entry-wrapper.no-userpic .entry .contents .userpic,
    .comment-wrapper.no-userpic .comment .contents .userpic {
        display: none;
        }

with

    .entry-wrapper.no-userpic .entry .contents .poster,
    .comment-wrapper.no-userpic .comment .contents .poster {
        margin-left: 0;
        }

should make everything ok.
