Most new players that come to Crafty Mynes came just for vanilla, yet many of them don't understand 1.9 features. I think it would help a lot of new players if we nudged them in the right direction to understand cool new things (especially showing people how to turn on the attack indicator). This could be accomplished in a few ways.

• Upon joining the server for the first time, players could receive a book titled 1.9 that explains all the features
• The server could have a serverplz command and/or a random text with a link to a page explaining it

Although the latter of these may be very difficult for Crafty to add.
I just think people are getting less and less willing to explain over and over the same information that people should know. And they should know, it's not really our problem, but it might be the difference between a new player staying, or leaving.
