Not a bug but... the huge difference in font size between quotes and posted text is silly and extremely unfriendly to people with vision problems who use larger fonts.

Quotes should show the username of the person quoted.

The quoted text being larger than the actual post has annoyed me from day one. I was sure it was just a temporary glitch, but months later it remains unchanged, so obviously somebody thinks IT SOMEHOW MAKES SENSE TO HAVE THE QUOTED TEXT SHOUTING EVEN THOUGH ITS PURPOSE IS ONLY TO GIVE CONTEXT TO THE POST WHICH FOLLOWSand the posted text itself is somewhat lost on the page, even though it is the entire point of the forum, it's what we come here to read,

and then you think this is a continuation of my post, but it's difficult to understand how it relates to my post until you realise that it isn't actually part of the post, it's my signature, a pretentious quote or something which is confusing the first time you read it, and every time after that it's just plain fucking annoying and you have to turn everyone's signatures off to make it go away.

Make the quoted text LESS visually dominant (LESS, not more) than the post which follows, it's purpose is secondary to the post.

Give the name of the person being quoted. As well as being polite, it is helpful.

Draw some sort of line after the posted text and before the signature so the eye doesn't just run uninterrupted into the signature in every post in every thread. Make the signature text LESS dominant than the post text. Signatures serve a purpose (supplementary links and background info) but they are useless if they are so annoying that they have to be turned off.

Really, why is this basic stuff so difficult? Even with all the great precedent, a million examples of forums which work really well out there, why did Rendo have to ignore all that and start from scratch inventing one which fails on almost every level? Welcome to the new improved Rendo forums, really awkward to read and really hard to post in. Money well spent, I'd say.
