Have you noticed this new "notifications" icon under the banner? => 

Have you ever missed some messages that were posted on one of your drawing? Now you'll get notified when someone posts on your gallery, and you'll be able to reply immediately!

You'll also get notified when drawings you've submitted have been accepted, or when you get a private message... (see the full list below)

In addition to these, if you use either Google Chrome or Firefox, you'll get that kind of alert :

These notifications are displayed even if you're not currently browsing the site! All you need to do is to leave a tab open with Animation Source. That way, you can do anything else on your computer and you'll get an alert whenever something happens.
It may also work on your smartphone or tablet if you use Chrome!

Of course, if you'd prefer not be notified, you can change this by editing your profile on the site.

The list of all the possible notifications currently is :

- Receiving a private message,
- Creation (fanart, fanfic, character...) being accepted or rejected,
- Message posted on your gallery,
- Message posted as a reply to your comment,
- Message posted on a forum topic that you watch

Most likely there will be bugs, so let me know if you find any.
Also, if you've got ideas on interesting things you'd like to get notified about, let me know!
