What are the best LinkedIn groups for job hunters in investment and wealth management?

I'm collecting recommendations for LinkedIn groups that are helpful for job hunters in investment and wealth management.

If you name a group, I'd like to know WHY you recommend it. Is it good because it shares job postings? Does it give great job hunting advice? Or does something else make it stand out?

This is for a post on my blog, so please mention if it's okay to quote you by name and affiliation (or field in which you're job hunting). If you prefer, you can make your comment on LinkedIn.

To get you started, here are the names of some LinkedIn groups that may be helpful:
* Family Offices Group
* Financial Services Career Group - eFinancial Careers
I occasionally read and enjoy Jon Jacobs' articles on eFinancial Careers,  even though I'm not job hunting
* Hedge Fund Group
* Investment Professionals Group
* Mutual Fund and Investment Jobs & Careers

Thank you!
