One thing I am noticing while I browse this site is that a ton of older images are missing. Even stuff from 2013 is gone, imageshack and photobucket seem to be prime culprits. I personally find imagur to be very reliable.
Yeah, that happens on many forums that don't use attachment space. I use google, dropbox, and my own personal server, so I should be good.
That said, around here, the use of the work 'site' or 'main site' is usually a reference to content not on the forum/board, but this is a minor quibble.
