There is a more detailed answer though.
The index you see covers six separate forums, wood, plastic, card, scratch, history & completed so there are six separate indexes I need to update. That's a quick job and it's basically a cut and paste job of the the new entries on each forum page. From there, combining and sorting them is done on auto pilot!
Ideally, I should update the indexes as soon as someone creates a new entry, or before the new entries extend onto the second forum page. Once that happens, I have to update the index with the entries on page 2, then do it again with the entries on page 1.
I don't get chance to read all the entries so I've no way of spotting new ones. They just get picked up at the next update. (You could always send me a PM if you create a new entry and can't wait to tell the world!)
