I don't know if it was always like that and I just noticed it but when you quote somebody the quote author contains a colon after the name "name: said:".
You know why that was, Simon? When I originally wrote the bbcode parser, I made it say "name: quote body". At a certain point someone who shall remain nameless ;) spruced up the website a bit and added the "said:" in CSS, giving us two colons. Well spotted!
