I need a C# class library that does the following: 1.? Logon to Google. 2.? Attempting to access? <[login to view URL]>? should automatically prompt the login page. 3.? Grab an export of bookmarks from? <[login to view URL]>? or preferably the RSS feed at? <[login to view URL]> 4.? Process the retun values to generate a List object containing the values contained within the downloaded pages.
