Showthread title

[coberr]

I would to add also the foru display title in the SHOWTHREAD for the <title>

Currenly I have the following:
<title>{vb:raw thread.prefix_plain_html} {vb:raw thread.title}</title>

What Do I need to do in the vb4 to get the following result for the <title> tag.

Exaple on vbulletin.org/forum

<title> Showtrhead title - vB4 Programming Discussions </title>

What syntax I need to use in the <title> in SHOWTHREAD to get the:

<title>{vb:raw thread.prefix_plain_html} {vb:raw thread.title} - vB4 Programming Discussions </title>

Thanks.
