To post a new topic, you need to be logged in first.
Now click on the forum you want to post into and click on the "New Topic" button:

When viewing a post on the forums, there is a "Reply Topic" button

even if you are not logged in, but you will be asked to register/login if you click on this before you can reply.
Also,
be warned - even if you are previewing your new post/reply, your session is still timing out. You have 30 minutes to post - a good idea is to select all of the text in your post and do a "copy" before you click the "Submit" button. That way if it asks you to log back in again, you have it saved and can just "paste" it back in. If I could do something more about this I would - hopefully 30 minutes is long enough. An alternative is to write your post off line in an editor
first and paste it in.
