Just to get a better idea of what people want.

Personally i prefer code blocks to show all the code on the page, mainly because I'm a code monkey myself and i like to be able to read the entire code (and i hate the scrollbars)

Now is the time to voice your opinion on how the forum should behave.

you'll have a scrollbar anyways if it's more than a browser-window-length which is about what i'd say would be a good max lines limit visible - not saying 5 or 10 lines max, saying more like 40-50, just so that in topics with multiple long code items posted, the thread doesn't get immensely long
