Just something like:
HTML Code:
.forumbit_post .foruminfo .forumdata .datacontainer {
padding-left: 140px;
width: 80%;
}
Personally, I'd look into redoing the template for that category. And, I'd set the forums to have a min-width so users can't make their browsers small and 'break' the look. It's not going to be a 2 minute job, it's going to take some effort. And you can remove the RSS logo and green tick just by going what I posted above and setting display to none for that category.
