How to remove the space between forum title and threads?

[Spyike]

Check your current template and search for threadlist to be sure there is no css attribute with margin or padding, if not,

Add the following to your additional.css template:

.threadlist {
    margin-top: 0;
}
.threadlist {
    clear: both;
    display: block;
    float: left;
    width: 100%;
}
