In LEO, from the 'Preferences' page, select 'Edit profile'.
This page is where you can edit details about yourself and also how other users might view details about yourself.
There are two sections in particular on this page that might be relevant. Click 'Update profile' at the bottom of the page after you have made any changes to your settings.
Under 'Email display' ensure that this is set to 'Allow only other unit members to see my email address' or 'Allow everyone to see my email address'.
It is important that students in your unit can see your email address and are able to contact you this way if necessary. You can also choose to make your email address visible to anyone who has access to LEO.
Under 'User picture' it is possible to upload a profile picture of yourself. The profile picture will be available to students when they view your profile page. It will also be visible during some activities; when you post in a Forum for example.
Having a profile picture is useful for students to put a human face to their lecturer and for them to quickly associate 'important' posts in the Forums. I would also encourage students to upload their own profile pictures.
To upload a picture, drag a picture file into the box provided, or click on the 'plus' icon to browse for a file on your computer.
