Geeklog Forums

hello.

sorry for my bad english
i want to create a little mod in geeklog forum. i know that this forum is collecting ip's of every poster and saving it in forum database, but i don't know how to display these ip's in public. I only want show ip adresses of anonymous users. Which files must be modified to do that? Can anybody help me... I just want to know, what must be added and in which file. Thank you!

See the picture to see what i'm looking for
