lilgreenapples, if one of your peeps refuses to answer email it's because of one of two things:

1. Make sure the router is working. If it isn't they won't answer email. Just drop them on the router, and they will fix it.
2. Two others in the house are using the computer. You may not see them sitting there at the moment, but if you click on your other peeps you'll see that they are coming to use the computer for some reason.
