I've noticed a lot of posts from LBH's that use the excuse of "thanking" the WAW for something. That is why it's good to run it by the board when in doubt, b/c your heart has been through a lot and it's hard to see things like another person can.
I'm not saying there's anything wrong with good manners, but the W is pretty sharp and she'll spot an excuse at contact very quickly. So, I'd say whenever you are thinking of thanking her about something......ask yourself if you really just want a reason to contact her.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
