Hi, is there a plug in or code i can use so it would display the users primary group under his/hers avatar?
Just edit the postbit template of your theme.
All you need is change positions of postbit_avatar
postbit_usergroup.
huh? Is there just a code i can insert?
You would need a plugin to display the text based usergroup since the $post array only stores the usergroupid and not the usergroup title/name. You can get creative and use images and use those instead.
Moved to requests.
