Actually guys there is a simple way to do this. Using any version of Messenger Plus! or Messenger Plus! Live, click on the icon in your contact list, and then click on "Contact List Cleanup". The tool is VERY helpful, and works flawlessly. I've used it to monitor who still has me on their contact list, and who I don't ever talk to.
All you need to do is highlight all of your contacts and hit delete. However, it may or may not take it a few seconds or minutes depending on the amount of contacts you're deleting.
Thanks - I just did that on an old account of mine.
The only thing I wish WLM would do, is not tell you about who's added you to their list. It's really annoying being reminded of people who have you still on their contact list, and you don't speak to, and also idiots who have added you as spam (which has happened once or twice in the past). I wish all traces of these addresses could be removed off accounts. Does this annoy anyone else but me?
