[Plugin: Feedburner Email Widget] Nice Plugin, A Small Update

ok cool :), and you are welcome. Keep up the good work 🙂

Cheers

Hi Jan,

I did a little modification, code-cleanup and added a few features to your plugin. Now it’s much more user friendly. Here is the code for widget-feedburner-email.php file. You can roll this out as your next update.

I have fully tested it with WordPress 2.9.2

I would be happy to support this plugin and work on it with u if you can add me as a co-author in the plugin info. But if you don’t want to, Its ok 🙂
