Nowadays there are many online collage classes out there. A couple of days ago I happened to realize this one: Equine Nutrition by Dr Jo-Anne Murray of The University of Edinburgh. Details can be seen on its page. Coursera.org is one of the leading organisations in the field of online education. I'll be taking a computer class from them this fall.
Anyway... I just wanted you hear that equine nutrition course. Hope, this info might be useful for some members of the forum.
