Sorry in advance if this has been addressed but I'm at work and I can't really browse around... I'm curious if I could change my email address. I signed up using a username not knowing it would be my email address. I'm aware you can add up to 5 email addresses however I'm on a trail and I have that for 4 months and I am gonna pay for the service once it expires however when I try and add an email address they want to charge my card and I don't want it to be charged until the 4 month trial is over. Has anyone added an email address without being charged or anything along those lines? Thanks in advance.
