APMP - Association of Proposal Management Professionals

The Leading organization for proposal management is the APMP.  

They used to have lots of good free content, but now it seems like most of that is members only. 

There is still the great page with tips for MS Office Users and there is also the page with nice podcasts 

The APMP forum, however, sucks and you likely wont notice any new posts unless you visited it two haircuts ago!
