Here how you can make your comments track the IP of the poster (I couldn't find a topic for this, so I'm posting it here).
Create a new field in your gl_comments table called ip with the following setings: varchar(20), NULL default=0.0.0.0
Next, open your comments.php in ./public_html and find change to following code:
Text Formatted Code
DB_save ($_TABLES['comments'], 'sid,uid,comment,date,title,pid,type', "'$sid',$uid,'$comment',now(),'$title',$pid,'$type'")
into:
Text Formatted Code
DB_save ($_TABLES['comments'], 'sid,uid,comment,date,title,pid,type,ip', "'$sid',$uid,'$comment',now(),'$title',$pid,'$type','$ip'");
For now, it just saves the code into the table. It doesn't show when viewing a comment, I'm still working on that. I know that the Visitor Stats pluging does a similar thing, but I didn't have that installed at the time.
Use PhpMyAdmin to view the stored IP per comment.
Good luck,
