I saw a handful of searches on the MLM Blog with the following terms:

"Len Clements + Yoli"

When that type of thing comes up once, no biggie.  A dozen times from different people and there is a good chance there is something to it.

It looks like Len Clements is joining Corey Citron and the rest of the Yoli team.

Site:

Len Clements is our group's Team Leader… so mail or fax your apps into him ASAP… You can also scan them back in and email them to Len at LenYoli @ cox.net 

Len might be best known as the CEO of Marketwave Inc.  His Marketwave newsletter and more recently podcast are a great source source of intellectual information related to the MLM Industry. Len is an expert witness on the subject of Network Marketing.

I sent an email to Len and he got back to me quickly confirming that he has accepted a founding distributor position at Yoli. Len was initially a consultant and later decided to join with Daren Faulter and Robbie Fender along with Rick Eisele who Len got to know along the way.  Len did mention that a lot of blog posts (mine included) and message board are suggesting that Yoli is Corey Citron's company and apparently Corey became part of Yoli after the other three founders.
