I got an email, asking why the site was not letting them know via email when they received a private message here.
This software will do that -- but you must tell it to -- it doesn't do it automatically. You can set this notification (and lots of others) on the menu underneath your username in the top right corner. Go to Settings > Account Settings on the dropdown menu underneath your username in the top right corner. That will bring up this screen:
Click the link on the right for Notification Settings. That will bring up this screen -- note that I've scrolled down the page to show some of the things you can choose to be notified of:
By clicking in the appropriate column (as shown in this example for Private Messages), you can choose to be notified by an on-screen notice or via an email. It you have selected the on-screen notice, and you have allowed your browser to do that (it will ask first, the first time), it will slide out a notification in the bottom right corner of the screen -- regardless of whether you're on this site or not.
Once again, this software will do all kinds of things that the old site could not -- but it's a bit more complex, and in this case you must tell what you want it to do for you...
