We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
They might give limited use but I highly doubt they give silver members full access. Most of the apps added to XBL are free and I think silver members only get limited access to them so expect MS to do something similar with YouTube.
Yeah, as stated, it's another incentive to upgrade to Gold, along with Twitter and Facebook. If you don't like having to pay for Gold in order to access them, then just use the services for free on your PC?
