Re: [ADMIN] Minutes of 1 September 09 telecon

What exactly does an addendum to the minutes mean? Can you give examples
in previous minutes?

Also, why put this as an addendum into the Sept. 1 minutes if indeed it
was discussed on August 25?

I would be happy to make the changes; I'm just not sure that the
discussion would fit into the Sept. 1 minutes, especially since both the
referenced emails, and the threads they engendered, don't seem to have any
postings between August 17 and September 15.
