    Something like this:
    Code:java
    1. @EventHandler
    2. public void onInteract(PlayerInteractEvent event) {
    3. Block clicked = event.getClickedBlock();
    4. Player player = getPlayer();
    5. if(clicked != null) {
    6. if(clicked.getType().equals(Material.SIGN_POST) || clicked.getType().equals(Material.WALL_SIGN) {
    7. Sign sign = (Sign) clicked;
    8. sign.getLine(/* Whatever line number */);
    9. }
    10. }
    11. }

    Sure

    @EventHandler
    public void onInteract(PlayerInteractEvent event) {
    Block clicked = event.getClickedBlock();
    Player player = event.getPlayer();
    if(clicked != null) {
    if(clicked.getType().equals(Material.SIGN_POST) || clicked.getType().equals(Material.WALL_SIGN)) {
    Sign sign = (Sign) clicked;
    if (sign.getLine(1).equalsIgnoreCase("Post!")){
    sign.setLine(1, "Done");
    }

    }
    }
    }


    This gives errors on setLine and getLine cuz they're undefined for type Sign

    Change:
    Code:
    Sign sign = (Sign) clicked;
    to:
    Code:
    Sign sign = (Sign) clicked.getState();

    Question, i know the lines are like args, so the first line is line[0] but am i able to put something on a 5th line? line[4] and not have it erase when the server restarts?

    A fifth line! :confused:

    Never thought of what that might look like :/

    It wouldn't show, and most likely give an error, since it will try to write to it.
    If you want to attach information to the sign, just save the location and the information to your config.

    Well i know you can exceed the max number of letters on a sign and the server will remember what it all says, up until you restart server, then it goes by the numbers you can see
