ListCleaner (P9 Version) - by noroom
~~~~~~~~~~~~~~~~~~~~~~~~

Now you can delete unnecessary entries from your Messenger lists, to sign in
quicker than usually.

Often, when u sign in to Messenger, the server sends a list with containing
users who have permission to see you online, who do not have permission, who
have you on their contact list, and who you have on yours. Sometimes you delete 
some users, and people delete you from their list, too. Even though they don't 
have you on their list anymore, their email will stay on the list of people who
can see you online. Why allow them to see you online, if they don't have you on 
their list anymore? It is pointless to give them persmission to see your status
when they don't have the ability to do so.

Now, let's say you block someone and then delete that user from your list.
Imagine that the person you blocked also deletes you. That person's email will
stay in your block list, even though it is not likely they will talk to you,
because you are not on their contact list anymore.

This explanation can be confusing, but I hope you still find ListCleaner useful.

Each email you delete will remove about 40~50 characters from the data sent 
when receiving a new list.

Note: The first time you sign in after having used the program it might take a
      little bit longer than usual, but that is because the Messenger Client is
      downloading the new, shorter list. But after that signing in should always
      be faster than usual. :)
