Author's note:

My enormous essay on Snape's personality, with special reference to the evidence for his being especially nasty (or not), has been updated to take DH canon into account. You can find it on the fannish section of my website at www dot whitehound dot co dot uk slash Fanfic, under the title But Snape is just nasty, right?

Also on there you will find an essay called Fanfiction. net How-To. This is a guide to how to use ffn's story-upload and editing features. It includes lists of what characters will and will not display properly in story, message and review text, and examples of dozens of interesting section breaks which will display correctly in ffn story-text, and which you can copy-and-paste into your own stories.
