Skydrive Public folder problem – “Sorry, you don’t have permission to add files to this folder error”

Please help.

I've created a Skydrive folder (\Dropbox) and made it both 'Public' & Created a Link as 'View & Edit'. However unless I am Signed-In, I can't upload files to the folder via either created Link. I want for myself and other friends (& friends of friends who are not my friends) to be able to Upload, Download, View & Edit (incl. Delete) files in to this folder. 

The folder \Dropbox. My e = neilevans_mudie at hotmail dot com. I created the Links using the Sharing menu from using IE8 (8.0.6001.N) on Windows XP SP3.

This problem has forced me to become a 'Dropbox' customer but I desperately want to continue an effective usage of MS Skydrive since I am long-term MS Windows, MS Hotmail.com & Skydrive.live.com user!

I've read quite a lot of the forum threads and they usually end up with a support call to yourselves & an product specialist from MS 'fixing' the problem by tinkering either with the user account or Skydrive folder/files.

Look forward to hearing back from you and resolving my issue.

If you need to contact me directly please do so on my email (neilevans_mudie at hotmail dot com)
