Website revamp

I have been aware for some time that I needed to do some sort of redesign of my website: Livewyre.NET. This has finally been completed and the whole site now has a totally different look. I used some Web 2.0 design principles with my own particular slant ie. choosing a black background rather than a white one. I have taken the risk of using 'png' files for the graphics, and this means that IE 6.0 users may not see them as intended (specifically the transparent features), but I take the view that if folks choose NOT to use the latest available browsers, it's really not something I can take account of. I am a staunch Firefox convert, so don't get me started on IE...
Please take a look and let me know what you think of the new design
