I mean as a feature of this plugin.
I don't actually know the capabilities or limitations of Sponge, so I'm not sure if it's possible... But it would be a nice feature.
If you don't understand what I mean, then maybe I can sort of describe it...
Say I log onto an offline server and my username is Bob.
I would prefer my username to be Ted. I would then either use some command like "/username Ted" or "/login Ted " in order to accomplish my goal.
I seem to remember that this was available with some Bukkit plugin, but I'm unsure if the same thing could be accomplished with Sponge.
Anyway, thanks for discussing it with me. 'u'
