Adding extra text and center

[nahtnam]

Hi. The plugin is working fine for me but I have two problems. Is there a way to make it so that the advertisement is centered? I know I can add the center tags:

Code: [Select]

<center></center>

but I dont want to add that to EVERY SINGLE AD that I add. How can I add that to the "template" and make it so that happens every time automatically? I also want to add the word "Advertisement:" before the ad (centered) so that people know its an ad and not part of the post? I guess I would add this stuff to some sort of template file, but I dont know which one or where it is... Thank you for your help!

EDIT: I am using the latest SMFAd build with smf 1.1.9.
