If your mini-profile template is already customized and you've hit the variable limit for your template you're free to remove any lines from the code below if they contain information that you don't plan on using. For example, if you have no plans to ever add a user's IP to their mini-profile for staff reference you can remove <div class="mp-info ip">$[user.ip]</div> from the code and everything else will still work just fine.
