Can I change my site nickname?
You certainly can! Just keep in mind that your old nickname and URL will no longer work.
To change your site nickname, go to your Account Settings > Me tab. In the Account section, look for the "Nickname" field at the top. Type in whatever you'd like your new site nickname to be, then click "Save and Exit" in the header toolbar to ensure your changes are saved.
Your pictures and everything on your site will remain the same except the nickname and website URL. For example, if your nickname was previously "kerrysphotos," your old URL was kerrysphotos.smugmug.com and will no longer work. Your new URL will be mynewnickname.smugmug.com.
Don't forget to let your loyal fans know your URL address has changed!
