Hi Martin,
That to me is what modelling is all about. I do the same with my research.
If anybody needs something and I can help it is no trouble to send it to them.
A another good example to follow Neils:
I needed to purchase an old magazine from Ostend and the seller did not have Paypal. An email to a friend in Ostend and he paid for it.
I then sent the purchase price in Aus$ to my friend and he emailed back that I had sent too much but he used the rest to buy a couple of beers.
Result? Everyone wins and is happy.
regards
