Under the *site* section give your Friendica node a name other than "/my friend network/", you can change the icon and banner text and set the default mobile theme typically to /frost-mobile/. If you don't want your node to host a lot of accounts for people you don't know then you may want to set the register policy to "/requires approval/". For security it's probably a good idea only to host accounts for people who you actually know, rather than random strangers. Also be aware that the Beaglebone does not have a great deal of computational power or bandwidth and will not function well if there are hundreds of users using your node. If you're not federating with Diaspora or other sites then you may wish to select "/only allow Friendica contacts/". That improves the security of the system, since communication between Friendica nodes is always encrypted separately and in addition to the usual SSL encryption layer - which makes life interesting for the Surveillance State and at least keeps those cryptanalysts employed.
