Try tapping on your Avatar/Jeff Waldman which will take you to your forum profile info. Go down and tap edit and see what’s listed as your Nickname and Display name. On Display Name there should be a drop down menu that will have other choices. Or go down to the very bottom of the page and there’s a “Username” section that is greyed out. If any of the identifications is different than “Jeff Waldman” try those. Or if you recognize one as the right thing.
If none of this works, I would send an email off to support asap. It might still take until Monday, but could be faster. Good luck.
