Header text alignment in Gespaa

Hello,

I’m extremely new to this. I’ve installed the Gespaa theme from
http://www.ifelse.co.uk/gespaa

Can someone please tell me how to move the header text (site name) from the default centre position to the left and slightly lower than absolute top, as seen on that site. Thanks very much in advance.

On a related note, since this is my first post, I have been browsing the posts here for a day or three and I have to say, you people are amazingly talented. I won’t name any names yet, but I must admit that I have three or four favourites. keep up the great work!
