I think the coolest thing that has happened is that you can now , meaning that your credentials are no longer sent in the clear. This is great news for all the tin-foil-hat people out there like me :-). It's not that I was ever really worried about my old creds going in the clear (they are pretty low-value and easily changed) but it's good to know things are getting better.
This is my first post with the updated code, so we'll see how it goes. Basically I just had to delete the old .Text web reference, add a new Community Server web reference, and then patch up the code to use the new classes. Not too shabby at all 🙂
