I'm just a guy who plays Terraria who wants to help keep the wiki up to some standards of quality. Expect a lot of reverts of vandalism and misplaced/mistaken information, some rewording of awkward-sounding sentences, the occasional deletion proposal, and relatively few additions of new content. Some of the more outlandish 'references' might end up getting removed, too.
At some point, I'll figure out a way to extract placed-block textures from their files. Then I'll start adding that to item pages.
