Hi Goeff,
I used to send data to this site , but the problem was the way it was done .They sent me a small program which took a screen grab of the shiplotter page and then sent the data to this site .If I was typing some thing and this program took the grab , my cursor would vanish from the page I was typing on , this was realy not a good system , so unless the way of collecting data has changed to a different way I would think carefully.I know BruceS in Aberdeen stopped sharing his data for the same reason.

PS I am still waiting to find out how much the new owners paid for this site !!!
