I do still have 1 big long thread (i.e. no pages) but I do now have oldest post first so I can read top to bottom.
It is a bit annoying when I revist threads which I have red half of as I would like to see the bit I havn't read first IYSWIM.
It is also annoying when someone says "soandso said xyz below" when it is actually above for me.
BUt on balance I prefer top to bottom cos that is just sensible.....you don't find the Mail writing their articles bottom t top do you????
