I know you have the option for removing underlines from links in the Text Adventure mode, but how do I do it in the Game Book mode?

By using TA mode and making it look like a Game book.

I haven't tried it, but I'm guessing by adding new CSS to alter the link styling. Off the top of my head maybe you can add the CSS using Jay's new method (see the libraries sub-forum here), adding the code on the first page of the GB as a script.

In your "Script when entering page" script (Script tab for "game"), add a "Run Javascript" command. Then put this in the type-in box:

TurnOffHyperlinksUnderline ()

That should do it.

Thank you.
