Wordpress (blogging utility) has a plugin that puts an "email this post" link next to each post. It requires an SMTP server, though, and the host doesn't provide one (neither does my ISP). Are services like smtp.com any good? They're 10 bucks a month -- more than half as much as the hosting plan itself -- and that's for 50 relays a day (conciavably we could get slashdotted or boingboinged or something, and go over the limit). Any other options?
