Can email appear in a user's profile?

forum/skins/default/templates/users/info.html is responsible to display user info. You can create your own template file, where lines

{% if can_view_private %} <tr> <td>{% trans "email" %}</td> <td> <a href="mailto:{{ view_user.email }}">{{ view_user.email }}</a> {% if not view_user.email_isvalid %} ({% trans "not validated" %}) {% ifequal request.user view_user %} </td></tr><tr><td></td><td><a href="{% url send_validation_email %}">{% trans "Send me a validation link." %}</a> {% endifequal %} {% endif %} </td> </tr> {% endif %}

are replaced with

<tr> <td>{% trans "email" %}</td> <td> <a href="mailto:{{ view_user.email }}">{{ view_user.email }}</a> {% if not view_user.email_isvalid %} ({% trans "not validated" %}) {% ifequal request.user view_user %} </td></tr><tr><td></td><td><a href="{% url send_validation_email %}">{% trans "Send me a validation link." %}</a> {% endifequal %} {% endif %} </td> </tr>
