Renaming worked - but the cards seem a little off center - i set the left margin to 2.8 cm, and now it seems centered - but I have to print and measure.
Normally, when doing something like this, I would control the centering by placing a big table the full width of margin-to-margin - then center elements inside the cell, but, obviously, what is needed here is a DTP application with rulers, such as MS Publisher, Adobe InDesign or the likes (there might be some free alternatives, I don't know).
I am working at getting a discounted copy of InDesign that will run on Vista (I need it for page setup of a Danish version of SBH, that I got permission to make), and if i get it soon, I could set up the pages if you (Yggdrasil) send me a picture file of the 4 elements needed (Lurker front and back, Treshold front and back)? I may even have an old version of Publisher, have to check - it should do the job, too....
