A few users report that each time they log in to Web Mail, they are presented with the First Time User screen asking for their name, and that this never gets saved and comes back next time.
A temporary solution for this problem is:
After you have completed the login and are in Web Mail, click Preferences / Web Mail Options and scroll to the bottom to the setting for "Your From Name". Make sure that is filled in with the name you want to appear in your messages, and then click the Save button.
That should save your name and prevent the First Time User screen from coming back. In the near future we will fix the bug where the name sometimes isn't being saved from that screen.
If you find that the solution described here does not work, please report it here.
