Hi Stefan,

I plan on starting next week on this topic (I guess that is tomorrow 
already :). I know Will is pretty busy in his regular life as well.

I will re-read your original email and the suggestions below and better 
review the pages you linked to originally and then hopefully be able to 
contribute more coherently after that. I confess I have been a little 
scattered these past couple of weeks.

I look forward to working on this with you, thank you for helping.
