Event marking for stimulus response applications: Skin Conductance with E-Prime

Hi Michael,

Thanks for your reply! I haven't been able to set it up such that triggers 
can be received (if I understand what that means). I imagine I would also 
utilize the parallel ports, however from what I have read so far some 
in-line code is required to tell E-Prime when to signal that an event has 
occurred (unless I am mistaken).

No worries about ranting haha--it's another way to share ideas. Also, what 
kind extra features are you referring to?
