Can we have a username other than our email name?
Were do you change it?
Go to your profile. Cancel that, they must be doing updates as profile does not show up for me right now. Give them some time to get the site fixed up. I know from experience it is not easy to handle a forum.
Press your profile pic > bottom right on wix , will take you to your profile page > under profile picture look for blue edit profile > you can change it there > hope this helps 🙏🇺🇸
