Regarding the automatic saving feature, I'd just have a question : if the redaction of the message is interrupted because the navigator crashed, or because the computer crashed, it means all the content will get lost, right ? And that wasn't the case with database saving, huh ?
Because unfortunately, when a redaction is interrupted, it's often because of that...
So what would you like, more espacially ? The notification list to be updated each time an answer is made, and to delete the previous notification concerning that topic ?
Or just that until you haven't seen a notification on a topic that you follow, you don't get notified for further replies ?
