RSSgenr8 is a hosted HTML to RSS Scraper Tool which dynamically generates a RSS feed from a HTML web page. So if your blogging tool does not support RSS (must be a very old-fashioned tool then) this offers a simple solution (although it seems to have problems with German umlauts). Ignoring my aversion against PHP and the unnecessary traffic such a tool generates, I installed it on my server in order to be able to subscribe to my sister's two blogs.
