You can install this theme by heading over here.
The space in the header for your username is limited, so if you’ve got a really long username you might notice it doesn’t look very special. If you’re handy with CSS you can go in and change the font size of #header h1 to something smaller, or if you’re really dedicated you can just change your username. But I wouldn’t expect that :P
Also, the description field is limited as well, so you might need to prune your bio a little!
Unfortunately I don’t have time to help everyone with their individual questions regarding the theme but if you have any bugs to report (ie: glitchy things are happening in different browsers) please let me know via my contact form.
