Profile Alerts - This is an add-on that is used to display alerts (popups) to the user when they enter a page with this block added, simlar to the one on concrete5 when a user has a message. If the user does not have javascript enable it will display as text where the block is. The alert will display a message "You have (count of new messages) new messages". The option to display a message once or everytime the page is accessed is a option.
If tested in other browsers let me know if it works.
