Remember the 12 Yr old who was sued by RIAA? Yeah, I do. Keep this in mind while "pinning" away...

<blockquote class='posterous_long_quote'>What’s even more frustrating in all of this is that Pinterest could make things at least a little easier on everybody by at least allowing people to re-pin internally on the site without concern for violating copyrights.&nbsp; Here is how:&nbsp; In Pinterest’s terms of use, by uploading photos to Pinterest, you specifically grant a license and right TO Pinterest to use your images on the site.&nbsp; They specifically state that this license is transferable (on a side note, this grant of license is actually another hot topic causing a buzz in the photography community). It would be so easy for them to simply, &nbsp;in turn, grant YOU a license to use images on the site that are posted by others, to the extent they hold a lawfully granted license.&nbsp; But they don’t do this.&nbsp; Instead, they say only that the user is granted a&nbsp; “limited, non-exclusive, non-transferable license, without the right to sublicense, to access, view, download and print any Pinterest Content solely for your personal and non-commercial purposes.” &nbsp; &nbsp;“Access, view, download and print.”&nbsp; The words “upload”, “pin”, “post”, “display” or similar terms are glaringly absent.&nbsp; Ugh.&nbsp;&nbsp; So&nbsp;still you have no right to publish work from another photographer even though Pinterest holds a license to all work uploaded to its site (at least to the extent the person posting had a right to transfer such license in the first place).</blockquote>

KNOWN as the REALLY IMPORTANT PART.
