Don't worry about deleting it this is a very laid back clan. You can start as many threads as you want the only thing I ask is if it is not destiny related keep it on the general chat thread that is pinned to announcements. Now to answer your question you can show as little or as much affiliation as you see fit. The clan tag DoD will automatically be added to your characters if your xbox live is linked to your profile here, any thing more than that is up to you of you choose to add the motto DoD 360 Charlie is good and as far as gamer tag changes that is up to you as it costs money.
