New plugin

Hi
Here is a link to my first plug-in, I offer it up for constructive criticism by my esteemed peers.
TeeJay’s Site News
It’s a small and, I believe, cute way of making announcements on your blog, for instance new features and can be turned on and off through the admin page.
I am not sure that it will be of great use to most people, but it was something I need and thought it would be a good way to learn.
Anyway download it if you will and please make comments. I can only get better by what I am doing wrong. Thanks
