Great answers. I am against giving your downline something for free with nothing in return. Its like enabling your kids.
I believe they need to earn, then they will appreciate it. I say that from experience. I had 4 co-op shares a month and I did give my downline a few members but they did not work the leads and they went away.
If your downline puts forth effort, then I say give them a few and see what they do with it.
