I like the alternate grey / white sections. It makes them easier to differentiate the posts. Have we seen all the skins yet? I only noticed two.
About the white space. I am on a desktop PC where I do the bulk of my work, so – naturally, this is what I use for visiting the forums. Is this forum optimized for mobile? Is that why so much white?
About the login. I have to go through unnecessary pages, and even if I bookmark the login page for this forum, it still takes me back to the SixBit home page where I have to select discussion from the drop-down menu. Can we have a ‘keep me logged in’ button? Pleeeeze?
