#introduceyourself/#introducemyself
The “introduceyourself/introducemyself” tag is for creating one introductory post that tells us about you. Users are encouraged to use this tag exclusively for that, and not to reuse it.
More information:
I used this tag because it is " a post that talks about the author, shares why they joined the community, mentions their goals or dreams, and in general provides an "about me" overview."
