I have participated in the 401k for a while, and on July 1, a Roth 401k became available, and I was on the site trying to figure out how to get that started. Am I able to do everything online if I am already doing a standard 401, or do I need to enroll in a Roth 401k completely separate? I was hoping to do it on the site, but had no luck with figuring it out. Thanks
