The way to edit your topic or post is after you've made your topic or post, if you look above your post, you will see a little box that says ACTIONS with a place beside it that says go.  Click on actions and scroll down to edit.  Choose edit then click on go.  That should take you to where you can edit your topic, including the title, or post.  If this does not work for you, let me, Anya, or Lewie_82 know and we will be glad to edit your post for you.  Thank you,
Anya
