The application has an integrated Community, so you can ask for help and share tips with other creators, as well as sharing your Characters with others.
On this channel you can ask questions of the community and development team. Be sure to be specific in your request, linking to example conversations and to the Character you're building will help get you more actionable feedback.
Be sure to check this documentation and the FAQ before asking, and be sure to note the community guidelines.
Once you've made an interesting public Character, and want to share it with others, you can post a description and a link to the Character with other users on this channel.
