I think there is a fine line between posting "too much" and nothing at all. When reading throughout the books, finding information that could be posted at the wiki can be a tad difficult at times.
This is why I hope that wikia users will notify the administrator of the page(s) whenever they suspect some information may be "out of place". In Rifts Wikia's case, I would avoid posting "stats" and "rules information", and stick to "general information" about skills, magic, and whatnot.
Take this, for example; "Spell X forces the player to withdraw". Would this be considered "rule information" regarding the gameplay? I believe it "kinda" is. But if we cannot write something simple as this, is there anything about Spell X that we 'could' write? I think not. So using this logic, I have deduced that pages/categories that are already made in the wiki are meant to be filled out.
Unless I am told otherwise, I will continue to provide information that does "not" consist of dice rolls, cost, percentages, etc., but I will provide the information of what X does.
Does this make sense? I hope so. @@
