Thanks so very much for the contributions to the Investure article, we were all (me, Eric and Windy) very impressed by your awesomeness.
I'll try and work your suggestions into the help articles, but to references using {{ref|?|<interview>|<number>|<question>}} the <interview> should be the ID of the interview page (for example the AoL Reddit Q&A is 708, the <number> should be one of the numbers in the black squares on that page, and the <question> is the text which is displayed, which should be the question being answered (for question numbers with multiple questions or long questions, it can be a paraphrased question which targets the thing being cited). So for example, Zach's question "If you burn Nicrosil, will it deplete Feruchemial Storages?" would be {{ref|?|708|12|Does burning Nicrosil drain metalminds of Feruchemical charge?}}.
If you want to mark a section or page as speculative, you can use the {{theory}} notice. If you notice a fact that could do with a reference, add {{cite}}. If there's a fact that needs rewording in some way that you cant fathom out, add {{clarify|with a little text that tells the next editor what might be wrong}}. If you think something's wrong, but aren't sure if you should remove it, add {{disputed|with a hint as to what might be wrong}}.
The {{ref|b|<book>|<x>|<y>}} is as follows: the <book> can be any of the books recognised by {{b}}, the x & y parameters are optional, and if used, get passed to {{c|<x>|<y>}}
One thing to remember is if you don't feel comfortable adding links or citations, or if you'd rather concentrate on the content rather than the 'meta' stuff like that, don't worry. Me and the other admins are often online, and will look through your edits for any 'extra' stuff that springs to mind. I certainly am more of a formatting person than a content guy.
