Mrs Trellis,, there is a way to get to the latest posting on a particular thread. At the top of the screen you have the address bar. If you look at it there is the usual
http://www.crosswordsolver.org/forum/ followed by a number which related to the particular thread you are on, in this case 159928/finding-a-thread. Delete the title, but not the whole address, so in this case you would delete the words finding-a-thread, and type the word offset/ followed by the number of posts less one. Then if you click on the arrow at the right of the address bar it will take you to the end of the thread. It looks more complicated than it is, cos if I can do it anyone can!
