Create ability to set own user name (I.e. alternative to email address)

Currently some varriant of my email address appears in the track changes and comments I make. I would rather have control over that and make it so it displays my name or initials so that the people I share these documents with know who I am and don't know my email address Otherwise great app that mees my needs.

They should be take this idea for good Commented

I just make my account and for a little mystake my email got wrong now if I forgot my password I don't have any support to remember me , I would like to change some details of my account but it's not possible. Cheers
