Help: Bucks (click)

To find threads that have dropped off the bottom of the list, go to the filterbox above the thread list on the main forum page, select 3 days (or however many you want) and click refresh.
If you type Bucks into the filter box at the same time, it will only bring up threads whose title contains that word, over the period stated.

Good luck with finding your way around. More info is available in the FAQ, a permathread which stays at the top of the thread list.
