LITTLE NEPHEW  I wrote Erik because I was having trouble testing Herald out by sending myself an email on another account, but from the same computer - no notification appeared. Then I had my daughter send me an email, and Herald worked perfectly! And by the way, Erik replied to my email in about one minute - donation will be forthcoming!

LITTLE NEPHEW  I've been using MailFX since the loss of mail appetizer. I don't like it nearly as much. I was excited to see Herald, but I too haven't had any luck installing. I've uninstalled & reinstalled, both times notified that the installation was successful. I'm ready to donate as soon as I can get a week or two of solid use. I'm running 10.6.1 on an Intel core 2 duo.

LITTLE NEPHEW  Holy damn - it's FREE for crying out loud! I agree with the developer; if you think it to be a lame name, and if the icon violates your aesthetic sensibilities, simply don't detract from your otherwise witty collection of apps by using it. It's like not voting for someone because they don't look presidential. Thanks for a well-designed, solid app.
