Excellent add-on Rated 4 out of 5 stars

This is EXACTLY what I've been waiting for -- a Thunderbird add-on that alerts me when I'm about to send an email that promises an attachment that I've forgotten to add. And sooner or later, EVERYONE does this! You can easily configure it to search for the words attached, attachment, "see attached" or whatever.

This review is for a previous version of the add-on (0.6.30).
