Yes just send 1 Steem to @steembasicincome and the person's name in the memo. You can send as much steem as you want to do multiple shares with one transaction if you wanted.
Example maybe you wanted to sponsor 4 people at once you would send 4 Steem with a memo of @person1, @person2, @person3, @person4
Or say you wanted to sponsor 1 person for 4 shares, then you just send 4 Steem with the one person's name in the memo.
Then you would get 4 shares also.
Just make sure the @ is in front of the person's steemit name. Nothing else goes in the memo other then the name(s) of those you are sponsoring. They are trying to automate this process and anything extra messes with that process.
Thanks @thedarkhorse for taking the time to clarify this for me. I think Ill be joining soon.
No problem glad to help!
