Rated 4 out of 5 stars
Great Add-on, asked for this in Netscape and Beta Thunderbird. Glad to see some one take it up, now i can maybe give up Seamonkey. Only gave 4 stars because it is lacking 2 things.
1. Add some sort of preview or thumb nail view so you know for sure your selecting the stationary you like.
2. Some way to read the embedded templates you already have.
Still Great Job
