Very minor (I think): When on desktop, in Chrome (at least), the cover images for each Group are color inversed. I assume this has something to do with the background for every page being black now, which is nice… except that this problem doesn’t happen on IE. I haven’t tried other browsers yet… will let you know when I can. Only a few Groups are using a cover image, anyway.
(btw I’ve tried png, jpg, and gif… all the same problem after uploading then refreshing the page.)
