I have a few points to make here.
1) Great Post; It should be stickied, and thank you for taking the time to show those who don't know how, how.
2) I think, though you did what you've done the best it has been done, you didn't actually say HOW TO INSTALL A MOD. You just gave us how to avoid, prevent, and fix problems, should they ever arise.
3)This post should be renamed: Mod Instalation, Tips and Tricks
Somebody please help me. Im trying to get the toomanyitmes file into my misc folder in .minecraft but I dont know how to drag files. I tried using extract to the specified folder but I have no idea how to use that either. Help please =(
I updated my Minecraft and realized that TMI was removed, so I tried to "reinstall" it. But when I try to delete META-INF it said that it corrupted. Now I plan to reinstall Minecraft and see if that would fix the problem. What should I have done?
What about deleting mods, I don't want to have to scroll through my whole minecraft.jar looking for the right class files and everything then deleting them. The whole time worrying im deleting a file thats needed to play vanilla. there has to be an easier way.
