I was wondering the same thing.

I've done searches in the past and posts always seem to disappear after a couple of months. This is regrettable, but I'm not sure they're doing anything different. I've gotten in the habit of saving a few of my really long-winded answers on my computer, because it seems like a number of questions, like "How to dig?", get asked again and again. Then I just cut and paste.

I think there was a 10th page that maybe was cut off?

If they really keep only 2 months, then that's a terrible waste.

I'd like to understand the logic of keeping only 2 months of archives. I'm sure I would disagree with it. :)

I just checked and it's currently 6 weeks. I agree that's too short, but I think they go by number of threads and just let anything drop off that goes over 10 pages (300 threads), or now in our case, 9x30=270 threads.
