That's true. If you post without logging in, it does log you in as you post. However, if your cookies aren't enabled, it won't be able to log you in (but the post will still go).
Now, of course you need to login to view private forums. <img src="https://www.ubbcentral.com/boards/images/graemlins/smile.gif" alt="" /> There's no way around that that I can think of.
It is possible to make login cookies expire at the end of the browser session but it does require a small code hack.
