I noticed that the e-mail client drop down menu in the Enigmail download page contains an item named "SeaMonkey 2.0", whereas the comment for that download file says "SeaMonkey 2.0.1 and newer only.".
I think that item name in the drop down menu should be changed to something like "SeaMonkey 2.0.1+" or at least "SeaMonkey 2.0.x".
Just my 2 cents.
