How to give a respons on a post?

Hello,

Mayby an obvious question.

Can someone tell me how to give a reply to a post?

I have an account and logged in.

I've read the guidelines but can't find it there.

In a post I will give a reply to the forum members in that post. When I do a review and save, I don't see my reply in that post.

I don't have check box 'Notify me..' - All comments - Replies...
