Enable and moderate discussions

Discussions are posts written on your space's public site and comments left on those posts and on problems. The Discussions card on Settings → General decides whether members may write any of it, and whether what they write is checked before or after it appears.

Two things have to be true before you can use the card. Your plan must include discussions — if it doesn't, the card isn't shown to anyone in the space, and only a change of plan brings it back (Quotas and limits, Why a section is missing). And you need permission to configure the space (Space → Configure).

Let members write

Open Settings → General.
Find the Discussions card.
Turn on the parts you want:
- Members can create posts — members may publish their own posts.
- Members can comment on posts — members may reply to posts.
- Members can comment on problems — members may leave comments on a problem's page.
Commit each toggle.

The three are independent. A common arrangement is to leave posts to administrators — announcements, editorials, news — and allow comments on them, so members can respond without starting threads of their own.

Choose how content is moderated

Post moderation on the same card has three values:

Setting	What happens
No moderation	Anything a member writes appears at once and stays.
Post-moderation	Content is published immediately and can be rejected afterwards.
Pre-moderation	Content is published only after someone approves it.

Pick by how much delay you can live with. Pre-moderation means nothing unwanted is ever visible, at the cost of someone having to work through the queue — a comment left overnight waits until morning. Post-moderation keeps a conversation moving and puts the work after the fact, which is usually right for a training space where the audience is known. No moderation is for spaces where every member is a colleague.

During a contest, remember that comments on a problem are visible to everyone who can see the problem. If you want participants to be able to ask something privately, that's what questions are for, not comments.

Reviewing and rejecting what members have written is done in the Content section — see Comments and moderation.

Sort posts into types

The card also links to Post types, the list of categories an author chooses from when writing a post — news, editorial, announcement, whatever suits your space. Setting them up is covered in Post types, and writing posts in Posts.

Turning discussions off again

Clearing the toggles stops members writing anything new. It does not delete what they wrote before; existing posts and comments remain where they are, and you remove them individually if you want them gone.
