I noticed a little bit ago that my bungie account got upgraded to bungie pro. Read the blog entry yesterday about the rendering and it stated if you were one of the lucky 2 million members upgraded, you now have rendering as well. Goto your file share on bungie.net and if under the video it says render, then you're set. If not...then I think it becomes available in July.
