Ah just had a quick look on the site and you are not allowed to add the tax if you are a sponsering a family member doing a overseas event. So thats why 2 people didnt do it, I think I will get her to add something to the page explaining it thou, so everyone else knows to do it, cos its all a bit misleading!

edit to say, if you dont pay uk tax you cant do it, which also rules those people out, Sue is katies aunt and works in the USA, Narf is her nan who is a oap and Alex is a poxy student lol.
