Hey, guys, great site. I've got a suggestion--give the dimensions of the cover photo on the profile page where users upload their cover page photo/pix. It would really help when selecting that "perfect" image for my cover.
OK, I've added a note to the icon for editing your cover photo with a 900x300 pixel recommendation. It will still work with other dimensions, but that resolution seemed to be the best for maintaining detail across all platforms (mobile, web, etc.)
