So, I just recently switched my website from postnuke over to WordPress. As part of the process, I wrote a simple PHP script to convert all of the entries from the postnuke site over to WordPress. Although postnuke is a pretty heavy-duty CMS, there might be a few people out there who will make the same switch, so I decided to clean up the script a little and post it on the site for anyone who needs it. You can get it here. I put it under the GPL, so you can probably use it with no worries. If you do use it, send me an email or post a comment or something. I should add that it would be generous to say that I'm a novice at PHP. I'm sure there's plenty I did wrong writing the script, but it works (for me), and that was enough.
