Curious...

As of the more recent Module Developers Guide done by M. Washington, I can not find any mention of the Inter-Module Communication interface.  In either Part 1 or Part 2.  I've done about every search on the PDFS I could think of, and still nothing.  Can you point out where it is covered?  Did it get a new name? Is it's use completely different in DNN 4 vs DNN 3?

I found an older (2006) version of the Module Developers Guide that does make mention of it.  I just wanted to get clarification for others, when they come searching for info on IMC.  Though it is covered, the original poster is correct in that it isn't covered much, either in print or online.

Thanks guys!!!  As always, solid work!
