Two quick questions:

1. Why does the Kano.is website log you out so quickly? It boots you after only about 10 mins.

2. I'm currently on the default "stratum+tcp://stratum.kano.is:3333".
As the closest sever to me is "stratum+tcp://uk.kano.is:3333" would there be much of an advantage in switching to the closer server?
A little detail would be good as while I realise pings would be important in something like online gaming but I don't understand how mining would matter much.

Thanks
