Invisibility/privacy
Not overly important - just an observation. Not sure if this is the intention; however if one chooses to be invisible when viewing one map, it defaults your privacy setting to the same for all other maps. And similarly if one selects the 'privacy' option on the community tab, it applies to all maps. That is, it makes you invisible whichever map you are on. Perhaps it should state invisibility across Debategraph, otherwise it implies that it is only for a particular map that the privacy option has been chosen (?)
