The only thing that keeps them from using the Google, is the fact that they are unaware of two things:
1) They don't know there is an update.
2) They don't know that they'll meet so many new friends if they get the update.

Earlier (somewhere on this board), I have posted the idea of using a tool to send an 'update now!'-like chat message in all 1.20 servers every 30 minutes or so. The next reply contained a link to the JCF thread about in-game spam that was sent by a similar tool that had leaked out (one that was still being developed and had no real purpose AFAICT, as I've never seen it ever after). I'm glad there's finally someone else thinking about getting the 1.20 players into the community. And I think the best way to do that, is by telling them there's an update. Just, for Christ's sake, don't leak the program this time.
