This list does not cater to what you care about, it caters to the 
topic as listed on the home page.

Read the home page of the list.  What are you reading into the 
title ?  99.99% of all PCB's are made with chemicals.  This is the 
RIGHT list for that.

If you want machine design, you don't go to electical engineers.  If 
you want to make a PCB you don't go to mechanical engineers and you 
don't go to chemical engineers to find out how to drill holes.  I 
imagine pcb design would get tossed off your list PDQ.  Why should 
all other lists but this one have a specific topic as stated on the 
home page?  Common sense should tell you where to go to get the best 
response.  Of course it starts where the idea starts.  And if your 
list started getting into the chemicals for making PCB's would you 
want to discuss that or would you tell them to come here ?  ie: go to 
where the experts are or people with similar interests.

I totally disagree.  How many on your list know the chemical 
reactions of the stuff for making PCB's ?  Wrong list for that.  How 
many on here know the stress and tortional calculations for 3/4 
CRS ?  You don't ask an EE for mechanical designs and you don't as 
ME's for Chemical properties and you don't ask a chemical engineer 
how to drill holes.  (seems I already said that, but it is worth 
repeating.)

I agree, but you seem to advocating that less mechanically inclined 
design your machines.  This list is not 90% mechanical and 10% 
electronics.  just the opposite.

I think the number of posts on the topics on here reflect the 
background and experiance and direction of the list members.  90% 
want to know about or handle chemcicals.

Look at any list, you go there to get answers or offer your help.  
What part of this list description has anything to do with mechancial 
machine design ?
