Yeah, it's been very frustrating for all of us, but at least Chris figured out that little fix for many many of the 404 errors....(remove /forums from the URL), but unfortunately there's still many that don't have that format and we haven't figured out how to get around it.
This software problem coincided with the rise of the FB VX group, so most of all activity is now on FB...but FB was never intended to be a searchable database and so any data listed there is virtually lost within a short period of time. The VX.info forum is the real meat of the database on VX stuff. I'm sure hoping we don't ever lose all that info.
