Well. I've been here for....over a month now, I think. Longer maybe. And I must say, I really still don't get Essence Mapping, though Eruheran's SEM /really/ helped, and I think I might give it a shot.
(I do not think with the mind of a Computer Programmer. At all. >.O)
But I have a question. How essential do you think Essence Mapping is? Do you think not mapping it would hurt your story in any way, or will it help smooth things out in a way that is more convenient? 
Interested in hearing your thoughts. 

I'm pretty sure I posted this in the right section. If not, so sorry.
