New postings above old ones on the forum walls

[General Roy]

Concise description:
Putting the newest postings at the top of the wall as standard.

Specifics:
I realise that one can have either the oldest postings at the top of the wall or the newest by clicking on the Ascending/Descending button. Only trouble is that my preference doesn't stay that way. In the school forums this is awkward, as I then either have to click on that button each time I go into the forum, or scroll down to the last posting, which would be my teacher's last entry (or my own).

So what I'd like to do, is having either Ascending or Descending as a preference that I could set.

This will improve the following aspects of the site:
It would make it easier to find the most relevant posting, rather than having to scroll through all the postings that I've already been through and that I'm no longer interested in.
