Customize fetch_error? or better solution
 

So I created my own Registration Page, and there are 3 cases that happen when the submit button is pressed.

1. The page has errors and returns to the current page with the errors.
2. The user hasn't clicked the agreed box and they are presented with the 'register_not_agreed' template.
3. The user successfully signs up and is presented with the 'registeremail' template. (for activation)

My problems lie with #2 and #3.

#2 has that standard "Message" box which is very ugly... I could edit the templates, but the message box is placed around them... I've looked into the code for fetch error but its doing some XML outputting (which I've never dealt with) and so I don't want to touch it.

#3 The same as #2, but there is the login menu above the Message box? Why is it there? How do I get rid of it? I dont want to be shown ever actually, The Members List, FAQ, Login, etc...
