Are there ways of migrating from one instance to another, or will I forever be tied to the one I chose if I don't want to create another account elsewhere? data import and export only goes so far

@rafl From what I've seen, there's not one currently, but it's something they're trying to figure out how to fit into the protocol, so it's not an outright impossibility. It'll be required if we want a system where folks don't disappear because other people got sick of the money and effort required to be a sysadmin.
