Update 5/3
Wow, I'm actually reviving one of my half-a-year-old beta's which has never been officially released yet! I've added some new stuff and improved some parts. Next to this it comes with an installer now. I'm aware Content Stealing uses quite some resources when you haven't cleared IE's cache for a long time. However, if you use WLM it will be faster.
It should actually be near-release now

Hey,
Before I release this program to the public, I'd like to share it with you. Please notify me of any suggestions/problems.
Custom Content Manager, or CCM, is a 3-in-1 program focused on custom content in MSN Messnger. It's not a plugin, but a standalone program.
Content downloader
This is the main part of the program, and allows you to install hundreds of
free display pictures, emoticons, and backgrounds. Just check any item you like, and they will be added to your own 'pack'. To add them to MSN fully
automatically, just press the 'collect your pack' button. You can then specify all the shortcuts for all selected emoticons, and view/remove all selected items.
MCO Manager
You all know of those leaked winks/moods I suppose. You can download them and add them to msn one by one. The disadvantage is that having hundreds of winks in your account will slow down MSN Messenger. With this tool you can select a directory containing .mco files, and preview them. If you like an item, click the install button and it will be installed without the need of the usual mcoinstall.exe+vbruntimes.
Content stealer
Steal your contacts' display pictures/custom emoticons, and add them automatically to msn (or save them to disk). Allows you to specify emoticon shortcuts before adding them, as well as the option to use a DP directly as your own DP.
Now also works for Windows Live Messenger
Thanks to
