It's a common point of debate (and finger-pointing) within a company : the sales team says they don't get useful information from marketing, while marketing says that sales people don't use the materials already produced.
The American Marketing Association has created a new online forum that addresses this sometimes difficult, but always important interaction between marketing and sales organizations.
The main portion of the site contains a blog and the opportunity to register for Webcasts. Register as a user on the site and gain access to archived presentations and other content. You can gain useful information, but keep in mind that many of these Webcasts and content submissions are sponsored or presented by vendors of marketing-related products.
