Compatibility

The javascript has been tested on Firefox and Internet Explorer, and should work on both.

I am aware that the CSS doesn't look quite right on IE, but it's legible and functional and I have better things to do than wrestle with IE's idiosyncracies.

Programming notes

The remote mostly uses Javascript, but loads the blog list with PHP first and uses that to construct the HTML and Javascript for the page. Blog addresses are stored in a Javascript array. It keeps track of the current blog using a Javascript variable, incrementing that each time and going to the next blog using the array, rather than using ?action= links to the blog list page (to save on server load).

Needless to say, it won't work without Javascript enabled.
