Hi Joe, thank you. I just had a bit of a Google and found a bit more info about this. Thuis would actually come in handy, as I can use these UTM tags on the share buttons that I have put on Sutton Mencap homepage, and on the Media Hub ahare Video buttons. As well as this, this mainly would be good to use this on our Email Newsletters and Facebook links as well. 

Here is the information about UTM Tags.
