i think it would be awesome if we could use css in parties. At the moment we're pretty limited on what we can do and edit, and without css scrolling i think some party pages and profiles are, eventually, going to get insanely long.
at the moment it's difficult to have a nice layout and include a lot of information. For example, rescharity at the moment can only have enough information on a page which will fit in the layout boxes. Any guides we create will really stretch the page (down). And it's also difficult to arrange layouts and text.
css in shops and profiles would be awesome as well.
but i don't know much about coding, so i'm probably the wrong person to argue the cause ^^;
