Personnal messenger ergonomy
Actually the personnal messenger module looks like a simple web mail application.
It uses the same vocabulary :
but there are some basic mail behaviour, you don't find on the Personnal Messenger.
On the outbox, you see one line for each recipient of your message. There're much lines, it's not usable, and not the common mail behaviour.
When you open a message, you don't see the list of people that receive too this message, and there are no Reply to all.
As for me, these are basic mail functions (not basic at all on a technical way, I know :s ) users will be really disapointed and I'm afraid they'll not make any effort to auto-adapt to this tool.
