I personally start to dislike the default JCF theme after the years (well I see it everytime I browse/visit as a guest) and what more, the borders look glitched with a brown and black tr/td on the tables. Shouldn't we use a better one as the default? I suggest Stijn's Firenze as he did a good job on that one, maybe with a more Jazzy logo or a edit from the old one. After all, the 'Firenze' style matches with the J2O colors but looks way better than the current default theme. Just a small suggestion.
