@theArchitect: To show/hide all signatures and/or avatars...

• User CP > Edit Options > Thread Display Options > and uncheck Show Signatures & Show Avatars
  
• Alternatively, and untested, but you could try the following instead. Find the following in step one:
  

  $nested_vbcollapse_user_sig = "sig_userid_".$post['userid']."_";
  $nested_vbcollapse_user_avt = "avt_userid_".$post['userid']."_";

  And replace with the following, and then repeat step four.
  

  $nested_vbcollapse_user_sig = "sig_userid_";
  $nested_vbcollapse_user_avt = "avt_userid_";
