This is really good, works perfectly for us. Two suggestions I would like to see implemented:
1. When you reach a certain amount of characters, the message just cuts off without any warning. Either A. it should be Twitter style where it tells you how many characters are remaining... or B. it should be like Facebook style where it shows the "more" button to see the entire post.
2. If there was a way to add this to the notification list that would be awesome as well.
I love it though, I hope you continue to support this add on because it's very very useful. It allows our staff to quickly resolve issues. We use to have a hidden forum for that, but this feature has made that Staff forum prehistoric in terms of efficiency.
