Can I change my web address later if I pick the wrong one?

Renaming your Get Menu address is not self-serve — ask us. It is treated carefully on purpose: the address is printed on every QR code and baked into every link you have already shared, so a rename breaks things already out in the world. There is usually a better answer anyway: if you own a domain, your menu can be served on it instead (Settings → Your own web address), and your Get Menu address keeps working and sends visitors on to the new one — so nothing you have printed is wasted.
