Is there any chance the Last Post time could use the 24 hour clock?
Sorry to be so picky, but I snatch a couple of minutes several times a day to view the board and this would make things so much easier to see where I left off last time.
Jem, once a topic has been read the page with moving arrows on changes from orange? to blue. If when you want to view a topic you click on the orange? page it will take you to the posts that you have not read.
It does not change until you leave the site and return later. I use two pc's, one in the office and one at home, because it recognises my details, if I read a topic at work and then log on at home the read topics have turned blue so I do not have to open that topic again.
