Rated 4 out of 5 stars

The Add-on is Excellent!!! It has some bugs, though, but it works for me almost perfectly in TB version 2.0.0.23 (20090812)
At first, I had a problem: 11/242 messages were saved, and then I went to see what was the problem and discovered that the 12th message had a strange sign within the subject... I've deleted that message, tried again... 241/241!!!
