Please note that we've added to the "About this community" blurb a request that group members post at least one discussion topic for every promotional topic. It's important to keep the balance here focused on discussion and engagement, and to prevent this community from becoming a dumping-ground for every "read me" link anyone has to share.
Just to be clear, a promo topic is a link with a request to read, buy, critique, or share (either explicit or implied). It's totally fair game to include a link to something of yours with a discussion topic, as long as the post is starting a discussion (i.e., it includes a question or statement that goes beyond your particular material).
For example, if you link to a self-published novel saying "it's free today on Amazon", that's self-promotion; if you link to a self-published novel saying "what do you think about self-publishing?", that's discussion — no one has to click through to your book to participate in the discussion, but if they do, it might inform discussion-enhancing comments about quality and presentation.
Thank you for your support in keeping this community interesting and welcoming.
