When posting a Code fragment, one is presented with a TEXTAREA labeled "Code", which might lead one to believe that it suffices to merely paste in a code fragment. Alas, fragments do in fact require <CODE> tags, but once you post, you can't edit the node. Aaaargh!

I suggest that either <CODE> tags be inserted automagically if needed, or that the text area be labeled

Code (please remember to add <CODE> tags)

I'd be surpised if this hasn't been mentioned before.
