This means if you are new and vote for $0.01 then you have 5 votes of the same power coming your way in the future from other people doing the same thing.
Don't expect to get rich from this, but you can go through the other posts of people that are already using it and vote for the ones you like, and it will be up to 5x better than just upvoting yourself all the time!
The signup is very simple, just need private posting key from wallet, I have talked to the developer in length and he is very concerned with security so no active keys will ever be used here and key is not serverside it stays on your computer, so give it a try to get some extra upvotes on your posts.
Here is a helpful video, which shows how to register.
