You don't need to have that reputation to join our team, all you need to have is 100 steem power. You have now 21 and if you convert those 12 steem dollar into steem and power up, you will have 33. so you need more 67 steem power and you can join us.

But I see that you are not upvoting people, with the upvote you can also earn some steem power from your curation, if you upvote let say, about 5 people a day, it will be good for you and your earning will be better, but try to always keep your voting power at about 100%, that means, when you upvote someone wait some time before upvoting other, you can check your voting power here : https://steemworld.org/@melanie0625
