Just use your browser.

This is just a poorly organized and often crashing portal to the Tekkit Wiki.
The tips really are just general advice with no options for more in depth information.
The search feature doesnt look for anything not beginning exactly as youre typing. "engine" returns no results. Combined with random crashes every 15 seconds or so of scrolling you have to rely on luck to find anything you dont already know about. If that item is even in the list. I couldnt find any thermal expansion items in here.
As I said this is just a portal for the wiki. There is almost no offline content.

This gets 2 stars because of a nice design. But the content and usefulness is crap.
