There’s a revamp of an old plugin over at HeadSpace 2, and a new (not foolproof) Anti-Email Spam plugin.
HeadSpace 2 cleans up my oldest plugin, and gives it a nice administrative interface along with several nice new features. The Anti-Email spam plugin was some code that I developed for client that I thought might make a handy plugin for some people. It replaces any email addresses in a post with an encoded version that should fool spam harvesting software.
