Currently the IM doesn't work and I used to use it a lot because of the history and the small sound notifications it had, sadly I can't use this anymore (if I recall it got replaced by the browser notification pop-ups) and the browser notification system is the only thing we have at the moment which does not have a history or bring any sound so if you were to be playing a game you would not notice the pop-up until you tabbed down.
I don't know the exact reason it does not work anymore, maybe it's a browser update which might've screwed with it but it's a very useful tool for people who handle a lot of pms/gold.
What do you think?
Is it not worth the time to fix it?
Did you find it helpful when it was working?
Which one do you prefer (pop-ups or IM)?
