Comment 3 for bug 1367539

Tested on "1.10.0dev (2014091800)" AND "master" branch. With or without the patch, the user still do not receive a new notification after the admin changed the quota threshold. Below are the steps that I did.

Logged in as admin.
Go to Administration
Go to Users
Add User called “Jen”
Set up File quota to “10” MB
Create User
Go to Extensions
Plugin type: artefact → File (Configuration)
Default user quota
Set user Quota notification threshold to “50%”
Save settings
Log out as admin
Log in as user “Jen”
Go to Content
Go to Files
Add File until user pass their threshold quota above “60%”
Check email for notification of File storage almost full
Log out as user “Jen”
