Photoshop.com and its advanced features was shut down last year, iwantitfixed. I'm not aware of any way for your to receive premium content for version 10 anymore.
Are you referring to the photoshop.com plus members only Content or other?
As SG says, you do not have access to Photoshop Elements 10 photoshop.com plus members only Content which was available to you as a user of Premiere Elements and a paid member of photoshop.com plus when it existed (it does not any more)..
Interestingly, that old photoshop.com plus member only content can be found in recent version as coming with the recent version (no strings attached).
If you are interested in getting the Premiere Elements 10 Content (NOT related to photoshop.com "plus" only), please see the following which gives how to details..
Someone else asked that question today. Was that you also?
