How to get Forum Category Names Centered?

[Birute]

The Forum Category Names are aligned to the left, how do I get them centered?

In the Style Manager, custom template, forumdisplay.css there is:

}

.forumbits .forumhead h2 span.forumtitle {
width: 76%;
text-indent: {vb:stylevar padding};
}

.forumbits .forumhead h2 span.forumlastpost {
width: 20%;
}

and

}

.forumbits .forumbit_nopost .forumhead span.forumtitle {
text-indent: 0;
}

Would I add somewhere vb: stylevar center?
