Actually, not a question but the answer to something I was about to ask because I was only looking at documentation (my mistake) on docs.rubygems.org & google. I found the answer looking at the gem commands. The question was:
Where is the remote server that RubyGems uses?
Answer - run the command:
gem sources -- gives the info and allows you to add/remove remote sources. Also running
gem environment -- will produce more information.
