1. I'm unable to list members by a specific profile type when I create the menu item. It can only list "all members". How can I achieve this?
2. I would like some details/fields to be shown when listing the members. Currently the members are only listed with their name. I would like to show "About me" field for example. How can this be included?
Both these are quite important requirements for me. I hope Jomsocial team can provide the needed code to do this.
1. I am sorry we dont have it right now, but we will try to create it in version 3.3..
2. You need hack the code and use Jomsocial User Object to achive this, read here for more information
