The columns bbcode is for splitting text into multiple columns.
[ columns=X]Text in X columns[ /columns]
It is especially useful for displaying long lists, for example in a CS.

This is supported by most browsers, except one. Can you guess which?

The command is sadly ignored in IE... until the next version, hopefully. That means if you're using IE, you will see the usual long list. Nothing I can do there except urge you to switch.
