I spend 35 hours developing new alert system. New alert system include all kinds of alerts and very neat.
1. Support languages. You can easily translate all messages to different language.
2. Support type recognition. You can create different messages for every content type by simply creating file with the same name but start with 23- prefix, where 23 is ID of content type.
3. Messages are HTML format and looks very neat
4. There is action links in admin alerts, which allow delete, publish,
