Hi all,
this is a trick I found to enable "folder sharing" and other disabled-by-default wlm features, especially for non-american users.
Just login into your passport account profile (www.passport.net) and change your country from your real one to "USA" in the personal data section, then save and exit.
Now log off and login again in wlm and you will find all options available, including folder sharing and all the grayed out options in the settings menu (video carousel for example).
I think this trick can be useful especially for testers because mp!l is intended to be tested on full-working version of wlm to find how many bugs we can
I tried this trick myself and it works like a charm (I'm italian)
