Random name selector

I am a Spanish teacher and use this site to randomly choose questions in Spanish. When I save the url, accent marks and special punctuation come back as code - unreadable. Could this be fixed so I can save sets without re-typing for each class?

Most of the names on here are Oriental or latino/latina. I would like more American sounding names and maybe even some Australian names would be great. Just more variety in general would be awesome.

The Go button doesn't do anything when I click on it. Also, when I try to change the names it doesn't show the full list of names, the top part is covered by the Go button. This worked great for me for a long time until the recent updates adding...

Freely share with the developers and the public -- thanks a bunch!

I don't know how I share it with my friends because it is very unclear how to do it.
