R.I.P. another classic forum. Welcome a slow replacement that looks like it came out of laser printer in eco mode - all bright white, with almost no shading and letters and simple shapes in place of pictures. I really really hate Flat social media-style Design.
I also think that the main site has been changed for the worse. Not just the white color, but also that the navigation menus pop up when I mouse over them (but not click): let's say I'm going from the left side to interact with the Search box, and several menus show all over the screen... I was wondering why there were no comments on the change at the old forum, but thought that it's probably not all that significant by itself.
