Playground RSS feed is broken

[per1234]

For the last 2.5 years it has been possible to subscribe to an RSS feed of the edits to the Arduino Playground: (http://forum.arduino.cc/index.php?topic=308747.msg2163746#msg2163746).

This feed has broken sometime in the last couple months (perhaps around the time of all the SSO related changes made to arduino.cc) due to an XML parsing error:
https://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fplayground.arduino.cc%2FSite%2FAllRecentChanges%3Faction%3Drss

This feed does not validate.

    line 1, column 1: XML parsing error: <unknown>:1:1: XML or text declaration not at start of entity [help]

         <?xml version="1.0" encoding="UTF-8"?>
         ^

From the source shown at the above page it appears there is a space or some other character before the start of the XML declaration, which I believe to be the cause of the problem.

I am subscribed to this feed and use it to monitor edits to the Playground for spam or vandalism and also to determine actively developed pages for prioritizing my editing work. Without this tool I'm am a less effective contributor to the Playground.

Closing as wontfix since Arduino decided to make the Arduino Playground readonly:
