Uh oh...

This topic has been hashed over many times on this list, and in the 
Legal group at g.d.o. I've included links to several past discussions 
below. There is one in particular from last year that I wasn't able to 
locate that also would be relevant, having 200 or more posts in it.


I don't mean to cut your topic short, but the issue has been covered 
extensively in the past, and I don't think it would serve much to go 
over all the 'non-lawyer' opinions help by members of this list for the 
umpteenth time.
