Wordpress: How to change post page titles?

[Ms Naughty]

Hi all
Haven't had much luck in finding info on this so I'm hoping someone here has a quick answer.

I can't find the setting on Wordpress to change what it puts in the <title> tags for each post page. This means that all my individual post pages have a title that says:
Ms Naughty Porn for Women Blog : Blog Archive : <Post name>

I want the post name to appear first.

Any suggestions on how to do this?

Thanks

Karen
