if you go into the base install directory: %appdata% go into the .techniclauncher/tekkit/mods: there are all of the mods with the version at the end of each mods name
If I understand the problem correctly, your macerator is just too slow and the engine keeps putting ores in it correct?
If so, here is a easy solution: Overclocker Upgrades.
Put a couple of them in it, and watch the money roll in :)
Im a little confused on what you are doing.
First: Tekkit Server is only for Minecraft 1.1 not 1.2.3
Second: You can join a tekkit server with have the tekkit launcher but you have to have all the same mods and item ids as the server
It would be easier if you use the Technic Launcher and play normal Vanilla 1.2.3 Minecraft and tekkit 1.1. Minecraft.
My post was an answer to why it isn't in the pack. Niavmai on the other, try and be a little bit more respectful to people. I mean come on, the guy asked a question you don't have to go off on him. It was just a question.
To be fair though, if you took the time to read, you would find out that the reason there is no SMP version is because Krapht is waiting for BC 3.X to become SMP so he can start modding for SMP.
Re: Is there a way to properly protect an area/chunks/spawn ?
I use the izone bukkit plugin and it works great. But then again I have used worldguard and it work too.
