craftbukkitforge is the most common one, I have tried using MCPC but it still does not seem to work..?
Common^ anyway you may have use the wrong mcpc version or used it wrong! mcpc is NOT a mod core mod library etc it is a server jar. To use mcpc and have it work
1. Move the current server jar out of the server directory or rename it.
2. Download mcpc for your minecraft version and use the latest stable build. 1.5.2 packs use 1.5.2 mcpc and 1.6.4 packs use 1.6.4 mcpc and so on
3. Put mcpc in the directory where the old server.jar was then rename it to what the server.jar was called
The only difference between mcpc and the original server.jar should be the file size of mcpc is much greater.
4. Start the server and mcpc will be used as the server.jar and it will work.
