Yes, this part is 'standard' stuff. Basically saying they can publish what you write on the site. No big deal.
You also grant us global nonexclusive adaptation and resale rights over any content and material submitted to the Site. These nonexclusive publishing license and resale/adaptation rights extend to any materials submitted "for publication" within the Site, including both message board postings and content submitted for uploading and subsequent publishing within non-message board portions of the Site.
This is where it is very different than other sites.
