I'm sorry if I wasn't clear and sounded like I was complaining.

We're running out of time to get a WG launched in time to have a first 
face to face meeting at TPAC. Although such a f2f isn't a must -have, we 
(the Team and I) thought this would be a good opportunity to get the WG 
truly going. From that point of view, we would rather not change the 
charter any further.

But if anyone made a concrete proposal on how to change the charter that 
would seem to gain general support rather than getting immediate push back 
from others on the list I would expect the Team to accommodate. That's why 
I said that the most productive thing to do is to propose specific 
changes. This remark wasn't directed to you in particular but to everyone 
on the list.

I hope this is clearer.
