Only Wombat can change her own posts, so you can either contact her and have her put up the correct information or post your own correction as of a certain date, and have her take hers down.
To post a question, go to the FAQs page and post a question. Then if you yourself are going to answer it, hit answer and answer it. Voila, it is a FAQ. I suggest you put the date on the updated sources, as that becomes a problem when situations change, for example, Iodine SOURCES AS OF SEPTEMBER 1, 2007.
