The server will be updated to 1.3 when bukkit is available to download. http://dl.bukkit.org/downloads/craftbukkit/ You can see the latest one until now is 1.2.5. Please wait until the bukkit team updates to 1.3. Thanks.
Have you ever considered using the tekkit pack? Its what me and my friends have on our server. It includes buildcraft and industrial craft. Allows you too have proper wiring set ups without redatone. Nuclear reactors a nd what not.
Envizz, I was going to ask the same but it means everyone needs to get technic... the only way being to get it though there really really buggy launcher which is supposed to stop piracy but in reality stops everyone from playing it
I have had no problems with it. Hassle free in comparison to before. Its seen me through two updates. xD
