Top of the seattube. Where the blue stops and the silver starts under your saddle.
You can take other measurements also and compare to the chart here. I don't imagine the frame changed much from 1995-1996.

That's what I figured, but watched a video on youtube where a guy was measuring a mtb and said to stop at that intersection, and that got me confused. That and I was thinking that since it's above the top tube, then it wouldn't affect the frame size since it's actually just an extension of the seat post. Plus the fact that my bike is 16.5" to that intersection, and 18" to the top. Seeing as they came in both sizes, it had me triple confused.

I have a feeling that diagram is inaccurate, however. Gotta be top of seat tube.
Measure Effective top tube : horizontal line from top center of headtube to center of seattube/seatpost. Should be 56cm for 16.5 and 58cm for 18" assuming '95s and '96s are the same.
This is a more crucial measurement of bike fit than any variation of seat tube measurement anyways.

Yea, but at a whooping 5'7", I'd figure if a 18" felt small, then I don't have it set up right. My first mtb experience was with a frame way to big. Didn't have to lean down at all, and felt good. But on this bike, and my 08 Trek 17.5" mtb, it just seems that I'm leaning forward and down more then I should. But I assume thats the aggressive stance you want when riding. Guess I need to ride a 19" frame, and see how it feels.

Ok, now we have some more useful info. When you said it felt kinda small, I assumed you meant cramped. Sounds like a shorter stem and maybe some riser bars are what you need (longer stems were more in fashion on older MTBs for some reason).
A larger frame means a longer top tube which will stretch you out even more.
But you're right, for more technical offroad riding a less upright position means better control.
