Hi. I just signed on for the trial period yesterday.  I've never built a website before and am new to all of this.  A couple of questions:  1) I chose a name at random to try 'site builder' with and don't like the domain name that I chose.  Is it possible for me to change it while I'm still in the trial period.  I would also like to change my Username and contact email address if possible.  Thanks for your help !
