I have no clue what the abandoned or lonely pages are. I will look into and see if I can answer you soon. If you would like to add a category, that is fine. You have proven that you really know your way around, and so that is fine. I would just ask that categories remain topical to the theme of tinWiki. Since tinWiki is based on the ATS website, I think an enviornmental category would be fine. There are plenty of conspiracy related topics that also relate to the enviornment. I would just think that we wouldn't want everybody creating categories, for the reasons I just stated.

As far as the wanted and requested pages. The requested pages are pages that members request, by editing the page you have linked to. The wanted page, are internal links that have not been created yet. You may write an article, for example a page on the Chupacabra (I am just using this as an example) and while writing you may use the term "cryptozoology". You might feel that the term cryptozoology deserves its own page on tinWiki, so you create an internal link by typing like this: [[cryptozoology]]. If the page does not exist yet it will turn the word red, indicating a non existant link, and then it also posts that link on the wanted page. Each time the link is created, it will count how many times it appears on the site. So on the wanted page it will read: Cryptozoology (5 links). (As an example).
