So, to me it looks like a valid RSS feed. However, I cannot get any RSS-reader to download the feed. Thunderbird 2 always gives "not a valid rss feed". I tried tons of other programs but I'm still not able to reed the feeds. (other than Firefox)
What are these XML buttons for, hence, how (can) I access these RSS-feeds?
