Hi Jteverett, For the clans name to display under your gamertag you need to make sure that you are a clanmate and not just a member. On the clans homepage there will be a tab to "set clan as.." either your active Xbox or PSN clan. Afterwards the founder may need to approve any requests to join depending on privacy settings. Another way to check to see if this step was completed properly is to check the clans roster list. You should see yourself listed there, and the clans name will appear in the pre-game lobby. Clan "tags" will only show up in post game reports. Hope this helps
