If you've been to the site before, you'll recognize that this is a new feature. The hope was to create a space for discussion about the contents of the site as well as topics more broadly.
A few things to keep in mind:
The forum feature is not the primary purpose of the site so, if it were to end up being destructive to the mission of the project, it could be removed.
Since I would want to ensure open but respectful conversations, posts and comments wouldn't be heavily moderated. It might become necessary therefore to create a paywall to ensure participants are of age. It would be a tiny amount just for age verification.
It should be kept in mind that the main goal of this website is to provide a space for those in the Church of Jesus Christ of Latter-day Saints to explore sexual ideas in an open, non-shaming, but not necessarily faith challenging way. Overt attempts to undermine someones faith generally do not fit within the purpose of this site or its founders. That said, some ideas presented are sure to be challenging and controversial to many in this site's intended audience. The hope is to have frank, honest discussion about sex within the Church and its culture, not lead anyone away from the Church.
