Add horizontal scrolling to [code] boxes

[#1]

Why don't the tags {code} {/code} - I have changed the brackets from square to curly - have the same effect as on the Usergroup Forums where a window with slide bars is created which cuts down the physical post length.

I think that's a css styling issue, we need to add 'overflow: scroll' to the code boxes. It shall be done...
