Currently, two users cannot access the same page at the same time as this locks the other user from accessing the same page. When this happens, the other user must manually call or email the other user to exit the locked page. It would be better to have a kill locked page button to easily unlock the locked page accessed by the other user issuing a message that the user wants to access the page. Another solution is a 1 minute time out rule on all page if idle to make it more accessible.
