Two weeks later and it's still password protected... The whole point of wikis is that the community can edit them If the Arduino staff isn't going to do anything about the issue then open it back up for editing and let the community deal with the spam. I for one am willing to put some time in deleting spam. What we really need is rss feeds for playground pages so that I can get notifications when a page is updated and immediately check for abuse. This appears to be possible with PmWiki PmWiki | PmWiki / RSS but from what I can tell it is not enabled on the playground so it will need some minimal effort from Arduino to make it happen.
