|A favourite colour combination|
Gadgets-wise, I've had quite a few for quite a while, but I've swapped things about a bit to include a subscribe by email option and an RSS feed of recent #cpd23 posts. My favourite Blogger gadget is the 'html/java' box, because it let's you do almost anything you want to - the 'Recently registered' box over on the #cpd23 blog is created using that Gadget with some code from Delicious (to create a 'linkroll') pasted in.
Another good way to customize your blog is to make use of the 'pages' option to add a fixed pages. I've got two: one for the basics, and one to show some some things I've proud of having done.
