As a server owner I would say some changes NEED to be made to ensure that out of the box Tekkit is secure, stable and user friendly. To name a few:
One of the previous updates contained (as many of you know) the NEI glitch. There were no warnings, patches or official information put around. If there were then i'm sure most people would have taken action where they didn't.
EE....there is not a lot to say, but if left on your server no matter how many patches you pile on there you WILL get griefed. And yet the only half-patches that are remotely easy to find are buried under piles of unrelated keywords.
Anyway I didn't plan on starting a rant, I am just saying that Tekkit should ultimately be as smooth as vanilla Minecraft. Nevertheless you have done a good job so far so keep improving!
