by default, the links between pages all have a paragraph break between them. I need to change that so there's no blank lines. Where's the code for that found?

This is done in the function DoPage in GamebookCore.aslx. You can import and edit this function, but it's a bit risky. It's the main function to build pages.

What's the comment character?

for a single line, it's:

// your comments

and for a block:

/* your comments */

at least with Text Adventure, but I doubt it's different in the Game Book

thanks. Worked. :)
