Now, today's second question.
I've been searching, and I actually did a search too (I just discovered the "search" option, wooo) to find out how I can modify my navigation without messing up the "previous" and "next" options from it. For what I've read so far, it seems to be a very hard task. I spent all day trying to do it by modifying my own codes. I didn't get an error when compiling, but nothing happened either. The new links I added to the navigation just wouldn't appear. It's been a short while since somebody asked this, I believe, but I wonder if any of you has achieved this (and if so, how?).
