As for the signature thing, this is the first time I've ever
heard it mentioned by anyone, but I suppose it's no big deal for me to avoid
quoting them.


A proper sig line begins with dash dash space (see mine). Proper newsreaders
can be set to filter out everything after a proper sig marker. Thus, anybody
who quotes something including the sig is liable to have the meat of their post
chopped off just before it begins.
