Note that if you use "//" or "#" for comment lines in a Poser library file the lines begining with these characters will be striped out if the file is resaved to a pallet from a Poser documment.

If you need to preserve text through a resave, a better idea is to add it as a material:

 material This is a copyright notice.<br></br>                {<br></br>           }

The if I remember right the maximum length for the text string (including spaces) is 60 characters. An advantage of using this method is that the copright notice (or what ever) will be displayed in the Material Priview drop down menu of the Surface Materials window.
