OK.
I just meant for you to check if you wanted to change anything to the intro' letter for lvl 0's you have...
...since I'll add it to the end of the letter I'll be sending out.
Concerning who is active etc., don't be too stressed about what you send out, since I write to all people I see who buy food from the TH (all new names) so that helps contact the active ones.
Whatever you do is better than nothing, and, as you say, there are a lot of the lvl 0's who give up (at least 75% I'd say)
