Anyone is welcome to join. Just need to leave a comment on a post asking to be added. [Here's the link to the most recent post](https://steemit.com/engagement/@abh12345/6bzkhk-the-curation-and-engagement-leagues-sponsored-by-carlgnash-and-paulag). Read through the rules at the top for league one and then part way down the post for league two. There aren't a lot, but the ones that do exist are important. After that, it's pretty much posting, commenting and curating.

I'm not sure what you mean by "can it be noticed," but hopefully I've answered your question. If not, please feel free to ask again. :)
