Homebrew PCBs

Well, seeing as I started this whole mess, it's time again for me to 
voice some comments and opinions...

Aligator (or some folks call them crocidile) clips are just fine and 
dandy for me.  They are what I can purchase, I know how to use them 
(even for purposes that are frowned upon).  I use the type with the 
insulation on them.  Yes, they pop off at times, yes I know that, so 
I deal with it.  If I had other types of clips on hand, I would 
probably have them too.

I have seen square pins used for "test points" on a variety of PCBs, 
at least that is what I think they are for.  Usually it's just a 
square pin poking up through the PCB - sometimes with a marking, 
sometimes not.  I figured if others use it for what I believe to be 
test pins, AND by combining it's function to that of a via, you get 
two "Features" out of one device.  

I have also seen other things used for test points, I don't know 
what they are called, but they are round and have a head on it - 
sort of looks like a nail.  I can see the benefit to those, but 
don't have them on hand, nor do I intentionally purchase them - 
don't know what they are called (Posts ?).

Otherwise, how is everyone doing with their ink jet systems?
