Subscribe mail minimum language tweak.
Florian Harms reported an issue
Just a small one: in the 1st mail after registration you are writing that on the 2nd mail the new contact need to react. In the following paragraph you write to react on this mail. It could be misunderstood... It would be better to set the weight on that mail and not the first one. Get "this mail" out and change it to either "that mail" or "the 2nd mail"...
