Thank you, Chestah007.
Let me try to talk it in detail.
MSG PLUS! provides a notification service in stead of MSN Messenger's notification. When a user enables it by check the check box "Enable MSG PLUS! notification windows" in preference-->Notification-->Popup Option, it can make a notification to him/her when specified event happens. But currently, I found it is hard to setting up the personalized event. For example, I have four group people in my contact list. I want to disable the OFFICE group online notification. First I have to disable the default online notification. Then check the online notification box for the people in the other three group one by one. I wonder if MSG Plus can provide group notification and group sound event when I right click group name and select "Messenger Plus! Extras". Currently, there are only two choice in this menu, Block Contacts in Group and Unblock Contacts in Group. It would be a great feature.
