I would like to subscribe to a Basecamp feed for my projects. However, it is an authenticated feed. See more: http://help.37signals.com/basecamp/questions/103 How do I use that type of feed back your RSS reader? Or, is there an add-on? I have spent an hour already looking all over your add-ons and all over the internet and I cannot find a free RSS Reader with authenticating ability. Thanks, James
