5.Karma mod

 This one is very tricky, because it takes a lot of time to install, and also we have to notice that there is an error in the instruction about the file path. When finish all the edit and copy step, we also have to switch the theme to the “prosilver” in order to make it works.

Modification from Arthur

Google Search Box –

This one is cool, because it includes the google search in my phpBB, but unfortunately it doesn’t works in the theme I choose, so I change the theme to prosilver.
