I think the best place to learn more about musing is to go and join the discord server. You can ask anything you want to know and unsure about.
I will try and summarize what and how musing works.
Musing is a question and answer platform linked to Steemit. You can ask and answer any thing you want to know. If it is of interest and is of a decent standard and quality you may be rewarded with an upvote by other users and musing. No votes are guaranteed and shouldn't be expected.
Plagiarism and spam is not allowed and if caught you could be banned or ignored. The musing platform is all about having fun and learning together and it is that simple.
If you are unsure about anything else ask a question ,as that what this place is all about.
