[Opensim-users] grid operation

Thu Dec 4 20:48:17 UTC 2008

Kyle,

excellent, truly. Thank you.

The only thing off the top off my head is that I would like to turn down the informal chatty tone like 5-8% - and as Diva said, be a bit more sparse on the value-laden words.
Other than that, pure love and goodness.

I will try to give you more detailed feedback tomorrow.
