Your main account settings tab will provide you ways to change the general information about your Academia account on profile. There are three separate sections that you can change from this tab.
Here you can show the name you would like to display on Academia. The name that you put here will show up not only on your profile, but also next to any papers you have co-authored. Please be aware that you can currently only enter single initials (no periods) in the middle initial field. You can also change this information from your edit profile dropdown.
Your Profile URL
The first half of your profile URL (http://team.academia.edu/Hannah42) is controlled by your affiliation. The second half (http://team.academia.edu/Hannah42) is controlled here. For example, if you would like your affiliation to read http://team.academia.edu/JQSmith, instead of http://team.academia.edu/JohnSmith40, you could change it here.
Your Time Zone
Change what times are displayed on your profile, so they match your local time.
