Wordpress sitemap plugin

I am using Wordpress myself as a blog engine and I started to develop some plugin to make it more comfy. When I started blogging with WP I used the Google XML Sitemap Plugin from Arne Brachhold, but I had two problem with that plugin. First of all, there was a couple of link in the sitemap and I don't like the idea to hack a free plugin to remove those links. The second problem was the resources. That plugin used a lot of memory because if I didn't set the priority it did an autocalculation. This part of the plugin was totally useless for me so started to build my own one. The plugin is very simple. You can set the priority of the Homepage,Posts,Pages,Categories,Archives,Tags,Author pages, ping the Google, Bing,Ask.com and gzip the sitemap. The priority has a default value and the plugin doesn't make any autocalculation. So feel free to use and please leave a comment if you find a bug. The plugin is hosted at the wordpress.org : Simple XML Sitemap
