swallowtail

Ok so I hope i can ask this queison. I would like to disable creeper damage. Now I have spawn-monsters=false. I have never had a server befor and this is just for me and a friend. I have done some reserce and have found that you can add World Guard and World Edit . However my server is run simply off the B-team server file and hamachi. When I open the folder there is no folder for plugins as seen on the videos I have watched. Is there a way I can type in a command to stop creeper explosions or do someting else to get rid of them so I can have the other monsters back? THank you for your time. Also are the tornadoes disabled? if no how can I do that?
