Search Engine Marketing Organizations?

Are there any major search engine marketing professional organizations?

[meta_PI]

Does anyone know of any search engine marketing professional organizations? Large, credible ones? I've seen the SEMPO (http://www.sempo.com) organization, but it's just getting started...

SEMPO may just be getting started (actually, it's been in the works for nearly a year now) but it's probably the one with the most chance of making a difference.

Other than that, there's really only AMA, WAIM, DMA

eMarketing Association (eMA) as well.

How about SEO Consultants and SEO Pros?

I feel they are good and well accreddited tooooooo.
