Password issues resolved.
I fixed the password issues.
Most of you should be able to login to the site with the username and password that you received last night.
Usernames with periods changed.
Exception: If the username that you received last night included a period, e.g. melissa.sachs or recruiter.esq, your new username includes a hyphen, e.g. melissa-sachs or recruiter-esq. You should be able to login to the site with your new username and the password you received last night.
If you're unsure whether the exception applies to you, please do not hesitate to ask.
Username v. display name
While I have your attention, I'll also point out the difference between your username and your display name.1
Your username is how you login to the site. You are not able to change this.
You may, however, change your display name. Your display name is how you look to the outside world. E.g., This is the name that shows up if you leave a comment when you are logged in.
Please let me know if you have any questions.
Enjoy the rest of your Sunday!
