Has it always been this way? Threads are falling into oblivion* in less than a Month. There has been some very useful reference and project threads here (some of which I have added to) that have been kicking around for a year or more with varying degrees of update frequency. Now they're all gone. :-(
It seems like a very bad feature to me. Especially in this section where, not only are contributions less frequent, but there is a wealth of old information, that's still very relevant today.
* Okay, you can dig through the archives for them. But 3 pages still seems like a needless and far too short lifespan to stay in the main section.
