I think the best thing to do would be to have obviously your uni cards with you on the day. If proof is needed beforehand however we should scan our cards and send them to the likes of potter or the irish contact.
As for experience if we treat this a bit like the North vs South charity x ball match then we should have the best of 3 or what ever matches on the day so people of all experience can play.
Photographers should also be present at the events along with local press. I will also be willing to try and get a feature on our uni's tv along with radio slots (can be done as I'll be a DJ next year) and also i will write an article for our uni's paper.
Also if we have this as a charity-esque event possibly?
I would also try and seek advice from the federation about ideas for the event in terms of possibly having it sanctioned if we prove that its a high class event. Because look at this way if we get this right we should be able to start a tradition for years to come.
Just a little of my 2p.
Potter you have an add on facebook
