My Kinja account is associated with my twitter but when I am at work I cannot log on because Twitter is blocked by my employer. I appear to be able to log in with a gmail account (as in the log in screen shows up instead of an error). Is there a way I can switch how I log on without creating a new Kinja account?

This probably isn't the best place to share this but I don't have posting privileges anywhere else and I'm not sure who would know the answer.
