First of all, thank you very much for your valuable reply on my post. Actually I first came to know about Steemit from social media. Especially from YouTube.

Then after doing a lot of research about Steemit, I came to know about some communities in which the newcomers community is one of them. That's basically where I came to know about introductory posts. Then I post my introduction.
I came to know about Achievement 2, 3 from newcomers community and also watched various videos about it on YouTube. After posting achievement 1 and achievement 2, post achievement 3. I hope I have given you the information that you want to know about. Thank you.
