If some monk didn't find my node as good, just remove it, don't put -- on it. I don't know why my node
http://www.perlmonks.org/?node_id=692670
was rated -7.
It makes me to feel bad about the system.
My intention was to do some programs of my own and to post it for views. But mistakenly I might have posted in Q&A section, the responsible people can discard it or take it or don't allow to post in Q&A section.
