It's about time that someone brought this matter up. This topic is of a subject of dire importance.
The wikis that center themselves around Divine RPG (of the RPG Immersion pack), are poorly written, and lack information. A large number of tools, utility items, plants, and blocks do not have pages explaining how they work.
In fact, some of these items are simply mentioned in a list, as if to say "Hey, this item here exists." To the reader's displeasure though, simply knowing that it's an item, just simply isn't enough info for him or her to use it properly.
If you know ANYTHING about the items which lack pages, or even items which currently DO have pages, but lack data, make an attempt to add the information to the page, or post it here (I guess...), while making sure that anyone who reads it will be aware of the particular item (so they perhaps could make the page).
We may have linked the Divine RPG page to a wiki, but it shows poorly on our behalf as wiki page editors, and Minecraft players, if that wiki itself is incomplete as well...
Disclaimer: I am simply a player who cares about the importance of having our data.
