Show HN: Send with Webmail

Just wrote my first Chrome extension - it sets webmail as the default handler for email links (rewrites mailto links to link to webmail). I had the opportunity recently to assist someone who was trying to set their AT&T webmail as the default email application, and I was unable to find any Chrome extension to make that work (there's an extension from Google, for Gmail only, that does this). Thus, this extension was created. So, this extension supports several webmail providers, including Gmail, Yahoo!, AT&T, Hotmail, etc. It also supports custom links, so for those of you running custom webmail installs, you can customize the rewriting with your own domain name and printf-style placeholders. Let me know what you think!
