New Look - A Work In Progress

I've been getting kind of sick of the look of the site of late, and have intended to do something about it for a while. Anyway, the time has come and I hope it looks, ummm... fresh. I'm going to be trying to sort a different header at some point once I get a little technical know-how/help behind me. I am slightly concerned that although the wider format looks great on my widescreen Mac, it may not look so great on a regular PC monitor. Let me know what you think or if there are any issues arising from the changes.
