I'm no longer actively maintaining this list of Harry Potter communities; it was last updated in 2009. Comments on this post are now frozen.
newbieguide is closed to new entries, so I can't turn the list over to anyone else here. If anyone would like to maintain a similar list elsewhere, and would like the HTML code for the list below as a starting point, email me at penknifewrites [at] aol.com; I'd be happy to pass it along.
