Lions are dangerous. Keep your distance!
"LIONS" on the other hand are not! They are "LinkedIn Open Networkers." It simply means that you can send them a connection request, and they will accept it. They will not "mark as SPAM."
This is an easy way to grow your connections FAST!
You can do a search for "LION" and start sending connection requests!
You'll find that most LIONS have thousands of connections!
Go for it! :-)
