Although not wholly concerning the thyroid, as so many of the endocrine systems are interlinked and a lot of us with thyroid problems also have adrenal dysfunction of some sort, I found this seminar which had a lot of useful information on there. For once, this is a doctor doing a seminar on how to help yourself and advocating prevention which I found quite refreshing!
