Why doesnt the email list set the reply field to be the list, and not 
the receiver. Am I the only one with a short enough attention span to 
constantly fuck that up?



Thanks for the feedback, I will look into GLdefine object, and any 
GEMGl_ objects (which I understand should all be GEM prepended to any 
normal openGL calls (ie the object name)?)

Do you guys (or anyone) have any simple example patches using the 
gemgl_*/gemdefine objects? Where do they fit in the em chain, etc?

Just curious so I can get started.
