This comment is about nicEdit / not about Pritlog itself:
When I type, I use to press Enter to feed a new line. In such case, nicEdit seems to generate a whole new paragraph placing my text between <P> </P>.
As gaps between lines were to high I started to insert <BR /> line breaks manually, until I discovered that Shift + Enter does the trick.
I don't know if this happens to everybody, or if Shift + Enter is already documented, but I just wanted to let you know.
