Feed The Beast Wiki (with some choice links)

[Lazybones]

Parts of the wiki are not very good and some have blank pages etc but knowing what NEI can do really helps

Not enough items NEI (can be toggled on and off under options if you do not like it)

Have all sorts of strange new items you do not know what to do with?

Similarly, if a user presses the "U" key while hovering over an item (or right-clicks on the item if not in cheat mode), NEI will show the item's usage (what crafting recipes it is used in).This function works in generally the same way as the recipe function.

Very handy! Thanks!

I'd been using a bunch of links I had from Tekkit and there are some differences that's for sure!
