Bre901,
Something more useful than going to the last post in a thread you might want to see is going to the point on the thread that is new since you last were on PPRuNe.
If you had a thread with 30 posts and the last 15 were new since you were last on, it would be much more useful if the thread opened and put you at post #16 than post #30.
Take Care,
Richard
