So, I want to make a group, but for some reason, I can't. I have everything filled out, but i still get "The provided clan name or clan tag is not acceptable, please choose another. (668)" So how does this work? is there something I have to do or no? Any help is appreciated.
That typically means your group name is failing validation, possibly due to profanity or characters that are not allowed. You will have to try using a different name.
