Re: Forum tweak?
If you go up to the top and hit the LOGIN link, yes you will go to the index.
However, in my test I hit "Reply" to a post in the Test section when logged out, and using the reply button took me through the login screen and returned me to the Reply form for that thread.
If you just want to read one thread you can bookmark it in your browser or "subscribe" and the link in the email will take you directly to that thread, even if there are new posts later.
Not sure if that's what you're looking for, but AFIK there is no "last thread" tracking.
