With the forum SW, there's a PHP/SQL thing going on, and as it is patched, the generated page ID's - including the home page - sometimes change. We're CONSTANTLY under attack by spammers and other goofballs, so there's a pretty constant stream of changes and tweaks as the site is defended both proactively and occasionally reactively.

"... PHP/SQL thing..."

That's all Greek to me, but as long as I can google ETS and get where I want to go, I am a happy camper...
