Unfortunately, this site only allows the use of a few blogging sites. I have limited resources, and servicing the hundreds of thousands of people currently using the site is towards the limit of them. Some sites are difficult to support for technical reasons: for example, some sites don't support RSS feeds or make it difficult for a robot to locate and retrieve them.

Of course, no guarantees! Contact me via email: grahame@angrygoats.net.
