title: Joomla! - Database tables related with users
body: <p>I wanna make my own registration form as i need to include extra fields for the users. And it seems that there isn't any FREE extensions that is able to do it. So i have to find out how to insert the users into the database.</p>
  
  <p>I have found out that there are 3 tables related with each other when creating a new user:
  1. jos_users
  2. jos_core_acl_aro
  3. jos_core_acl_groups_aro_map</p>
  
  <p>But i am running Joomla! 2.5.1 for my website and my database does not have jos_core_acl_aro and jos_core_acl_groups_aro_map tables!!</p>
  
  <p>May i know what are the tables to take note of when i'm doing my own registration form?</p>
  
  <p>Thanks in advance!</p>
