I've been "Thisismynickname" on The Knot for years. When I started using The Bump desktop version, it had my old e-mail username showing in the community instead (hello, internet privacy issue), so I set up a completely different account for the The Bump desktop with a different username.
When I was fiddling with my Bump app (linked to my TK e-mail address, what a mess), I discovered I could change my username so I did to nonexxxx because I don't use TB forums from the app.
Now... it's changed my TK username to nonexxxx.
Help! I'm really Thisismynickname. Thank you.
