1- I have created 21 Groups how can I give each group a different avatar, I tried editing the group but I could not change the avatar!
2- On the Who is Who page which is a Member List, it seems it showing the the username for the first and last name which for us looks more professional. How can I change this field if you can just tell me the file I need to edit I should be fine.
Unfortunately I'm not able to access your back-end so I can't debug this directly on your site, could you maybe update the details in site info box?
1)You need to hover mouse over group's avatar and then click it to change avatar.
2)I need to check this directly on your site.
3)there should be an "jon group" button on cover image, in all groups.
