I created a topic, now I want to edit the discussion line. I cant find a way to do that. Is there a way or it is what it is?

If you want to edit the title, you should be able to click on edit on the first post & change the title or post text.

Log in. Down in the lower right corner of your post is an icon of a folder with an eraser. Click on that icon and an edit window will open. Edit away.

got it. Thanks
