Hello Joseph!:
Oxwall Provides Great Ways to Help the Admin/Users connect to each other.
if someone account got Hacked, you can go to your database and edit the password of the user there example in PHPmyAdmin you can view and edit passwords there except the passwords are encrypted for security issues.
Backup is Important! Back your files Every week, or Even everyday! :)
Hope this Helps you
Cheers,
Ronnel
