I am informed that the newest version of FireFox doesn’t show the “add RSS feed” button in the usual spot. My webmaster is aware of the issue and is going to be working on it. If you have other tire-kicking discoveries, please let me know – but be aware that fixes take a bit of time.
In the meanwhile, if you’re using Google reader, you can paste a URL into it by clicking the big “ADD A SUBSCRIPTION” button at the top left of the page.
