Pray tell, powers that be at IR.... Whatever will become of this priceless volume of tech support that is the AMS 4.0 user forum? Will it remain "live" on your server so that folks who are slow to adopt 5 will still have something that is at least a reference guide? I would argue that even if you stop supporting 4.0 at some point, it would be nice to maintain the information herein.
Perhaps you can archive it to some sort of PDF format or something easily - is there a utility that can handle that job?
In either case, I'm sure it would be missed if it were to disappear, even after awhile.
