But it won't work without nick being present.

Basically his css hack on his name to increase it's size (Let's just ignore any possible rule violations for now) is applied to the "Online" bar as well as his profile. Is there anything we can do to confine the css so it won't effect the more static elements of the board? I am curious is there is a quick fix for it.

The only way we can curtail some of these overly exotic css is to store it on the board's side and scrub it for anything out of bounds. Right now I don't think of it as a priority as we have higher priority things to do.

Well I guess that would work if we have to implement something. However that example would only apply to size difference. (We could add more css to it of course).
Plus that's a less perm fix, and really a hack style solution.

What sucks is the CSS is all loaded and applied at once globally. If only HTML would allow 'sandboxing' of CSS. (I don't know how that would be possible, but it would be nice lol )

Perhaps.
We could filter out other issues later on too with a flexible filter system. One part php side, and one part JS (which can be disabled client side but I don't think that matters since it's mostly the cosmetic side).

This would come in handy mostly for the badges system, which is supposed to small cosmetic things that have no real permissions or power to them. Like for example a Badge could turn their username upside down, make it tiny, or make it bigger. etc (really bad examples based on the current issue)

As much as Nick is on I don't think it's an immediate issues at least.
