How to redirect join to pedit

where I should look to redirect succesful join to pedit.php and not to Avatar page? I guess it take me there since I didn't upload a picture during join.

I don't have time at the moment to write anything up for you. But i can tell you where you need to do it.

join.php near the bottom. The function showFinishPage handles this.

You basically need to rewrite that entire function to do whatever redirect you want.
