Once you register, it is highly recommended to set your user preferences, otherwise you may end up getting a ton of emails! To do this, go to "Profile" on the top navigation bar, or "My profile" on the upper left hand side of the page.
Once there, the first tab is "Information". The second tab is "Preferences". Make sure to decide what type of notifications you want. Unfortunately the defaults will send you emails whenever you receive a PM, a new topic is opened, or if someone replies to a topic you started. Apologies from the admin on this. We will work to correct this in the future, but for now, make sure to set your preferences!
While you are editing your profile, you can add additional information, a personal avatar, and many other options. Have fun customizing your character =)
