Hi, I've only had the script for a few days now and am still getting familiar with it.
One change I'm thinking of making is to change the mysql functions to mysqli. I've no immediate plans for the extra functionality this provides but may use prepared statements, as I integrate it in to my site, for security reasons. Not enitrely convinced as to whether its needed yet though. Do you think its necessary regarding the PT scripts or a little overkill.

Doesn't seem necessary to change sitemap, support or setup.php so would changing just the database.php to the below be sufficient.
