Re: [802.19] Minutes of the 802.19 TVWS call on August 25th.
Tuncer,
I think you could mention that Gerald provided a more detailed comments via email after the meeting, and then add in the comments. That would be a more accurate record of what happened.

Dear Gerald and Steve,
Before doing the changes, I would like to clarify a point. According
to my notes, Gerald's explanation during the teleconference wasn't so
detailed.
Are other attendees fine for adding such a long statement?
