Welcome @ayerz.
That is correct. Each week, you will receive Manna in your account. Also, anyone who signs up and verifies using your referral code entitles that person to 50% more Manna over the first year and you get paid out of the bonus pool each week for the same period.
Referring a large number of people is a great way to get yourself more Manna.
Yes part of the plan of action is to have Mannabase become a platform for people to blog upon. We are also looking at it as a venue where people and organizations can post their projects that require funding.
Great! It's good to know. I'll make referrals so more people will know. I'll also make a post about this maybe on weekend on my rest day. I hope it will grow big same as steemit. Thanks!
