When I was a member of Talk Board, we always posted if we'd be 'out of the office'. The debate would still continue, less the missing member.
Are you suggesting that it be a requirement that a member of TB be a road warrior? If so, how many miles per year or hotel nights would make you a candidate?
Many FT'ers have increased their miles and points balances in many ways. Some by credit cards. Some by maximizing bonus'. I know of one person that earns a sizeable amount of miles and points each year, and she doesn't fly.

I guess that makes her smarter than the rest of us.
I don't think we need to qualify TB requirements, other than what's already in place. I'm sure someone will post a link to those requirements.
