If you look behind the code that form your site, in the meta tags, amongst other stuff you should have something like this:

description:
keywords:
The first one is what I mean by title tag, when you look at the top of this forum for example you will see 'Webmaster Forums UK SEO SEM Webmaster Community Forum' that is the title tag for this forum.
Here is a suggested title tag for your main page:
