Generating Blogspot's feeds for more than one category

Suposse you have a blogpost blog like I do ;-) . Now suposse that someone wants to add a certain category of your blog into a planet. You could follow this instructions and that's all, you have your own feed for a special category.

But it happens that I blog about Debian. In english and in spanish. And there are two planets. So, I asked myself if I could filter by two categories (and perhaps, more). It's possible:

http://www.yourBlogName.blogspot.com/feeds/posts/default/-/category1/category2

So, for example, my spanish Debian posts would be:

http://www.perezmeyer.blogspot.com/feeds/posts/default/-/debian/español

(If the feed above fails, you are probably having a problem with the ñ in it. Try copying and pasting the URL feed).

And, in english:

http://www.perezmeyer.blogspot.com/feeds/posts/default/-/debian/english


Of course, if you happen to be interested in my KDE posts, just change debian with kde in the above URLs ;-)
