How to use FMD Server
In order to use the server you need to enter the settings of fmd on your phone. Register on the default server or change the url and register on a custom server.
When you register you need to enter a password, this password will be needed on the webpage to decrypt the locationdata.
When you are registered, everytime your phone gets located the location will also be transmitted to fmdserver.
After you have registered your phone, please note your custom userid somewhere safe. You need this id to locate your phone. The userid is a generated random id from the server so the data can be identified as yours. (Don't worry as long nobody knows whos id it is, nobody nows what data is yours and also it is encrypted)
You can also enable fmdserver(the checkbox at the top) that allows the application to constantly send the location to fmdserver.
