Hi @deanliu, You're an inspiration for a lot of users at Steemit. You're serving the Steemit community in the best possible way. I'm also learning and trying to contribute for the Steemit community in this platform and here is my recent effort: A Very Useful Steemit Tool For All (Step By Step Review). I'm sure you'll be generous enough to take a look at it and give your feedback. I believe this is going to help countless people. Lots of love!
