I love how you used facebook-like functionality, so upon the forum events every user can get addicted. Unlike FB one can learn alot from this place!
Still waiting for my 'night mode', although now I use the 'Dark Reader' plugin that f700es suggested (I find it a bit uncomfortable to switch it on/off through my chrome tabs)
also using a plugin forces the members to install something additional to prevent someone's website's drawback.
One may question then why FB doesn't use night mode.. well here I read alot and deal with lisp codes.. on FB I just watch puppies and cats.
