ok i got the thing installed properly.. except when i delete a user, it still exists in the other site... Does your script even enable full control of the user when edited on one site, it edits all?? or no?

If it is not deleted, this probably mean that you have not share them but simply replicated (clone) the tables.

When you share the users, like presented in the tutorial video, you should have an "infiinite" symbol beside the "tables" displayed with the JMS tool.
So check the slave site results to verify that you have correctly shared the MySQL tables.

they are shared, i did create a user and it did create it on both sites, but when i deleted the user it only deleted it on one.
which video are you refering to? #16 because i did exactly as that showed.

they are Definitivelly NOT shared.
Check that you have a link on the #__users table.

Check that you have the INFINITE symbol beside the table of the site where you expect to have the sharing and that they are connected to the expected DB.

To know exactly which table must be share for the users, go in the JMS templates and review the list of table to the action "share the users".
Share the joomla user means sharing of the tables
#__users
#__session
#__core_acl_%
