1. Don't re-host this rar file.  It just annoying when i try to update things.
2. All these models are avail online and free to download/distribute. 
3. Credit should always go to the original modeler. It is also free to give. 
4. EPIC games for not making rigging characters easy or fun.
5. Tiger Monkey Butt Munch

All chars in Ironguard, because I don't have a working Liandri skeleton for Maya (The 3D software).
Put files in your directory here to get these characters to work (On Vista/Win7).
