PhpBB Help Needed

Ok, so I want to build a bot within PhpBB using their Spider and Bot functionality. All I want the bot to do is add this html code after every 1st post on every topic. But, I can't find anywhere to edit the coding on him or anything. Can anybody help me with this issue? Thanks

Also I'm using Limewebs, so I really can't work on the server much. But, I can edit through the ACP.

Any help would be great.

Also I really didn't know where to post this, so I just kind of posted it here. If it is meant to be somewhere else sorry, just report it and a moderator can move it I guess

 

bump!
