Pros
Reputation of the organization is good, the name is reasonably well respected in the market. Educational programs are good to excellent. Chair community is truly a gift to the world. Very unselfish, sharing, caring, dedicated group of individuals. Resource speakers are excellent. HQ administrative assistance to chairs is good. If you've made your number, it's a wonderful way to stay involved and contribute and make some good money.
Cons
Economic model benefits the company more than the chair. Virtually no effective sales support after starting the initial group. Chair community is more a set of competitors than collaborators and the economic model supports that process. The online presence has gone downhill in the last two years.
