I've recently started a LAN server, so that when my friends come over to my house we can play some 2-Player Minecraft, and it's rather fun. I've been attempting to add mods to my server, but I'm afraid that unless I have clear-cut directions, I'll screw up my server in one way or the other, and I don't want to lose the progress me and my friends have already made.
I know I don't want Bukkit, that's just for their pluggins. I believe I need Modloader and ModloaderMP, but I'm not sure if I also need them on the client side, as well as other specific information and programs.
I feel like I'm making this harder then it's supposed to be, but if anyone could point me to a tutorial, or instruct me on how to do this, I would greatly appreciate it.
