Welcome aboard! As has been noted in another comment, be sure you follow community guidelines for your posts. When I started, communities did not even exist, and everything was guided by tags in posts: #writing, #fiction, genre-specific tags, etc.

I'll delegate some resource credits to your account to help you get started. Find other authors to follow, and be sure to build conversations when you comment. Authentic engagement with others tends to result in authentic engagement in return.
