For anyone else reading this

Never post private information on a public forum... including your actual email address or phone number

Scammers try to steal serial numbers and other private information by posing as Adobe employees... Never give your private information to someone who contacts you via PM (Private Message) or email until you are sure that person is an Adobe employee (see next)

When an employee asks for information (identified by a STAFF badge where my ACP badge shows) hover your mouse over their name and then click the Message option in the popup window to send a private email

Adobe does not use Skype... if someone asks you to talk to them via Skype to "help" you, immediately report their Adobe ID in https://forums.adobe.com/community/forumhelp/forum_comments/content so the person may be banned from the forums
