 * Hi, after I installed your plugin the following warning was displayed:
 * The plugin generated 12 characters of unexpected output during activation. If
   you notice “headers already sent” messages, problems with syndication feeds or
   other issues, try deactivating or removing this plugin.

 * Hi, I am sorry about that, I will update the plugin asap (within this week).
 * If you’re in a hurry, you can fix it on your end: _the tt-subscribe.php has MILES
   of empty lines after your closing PHP tag. That’s why you’re getting the headers
   already sent errors 🙂_
 * By that: you can delete the EMPTY LINES after the `?>` tag.
 * Thank you for using my plugin!
