Important Community Announcement
Greetings Adobe Forums User,
We are excited to announce we will be delivering a modern community experience to you in the very near future!
For our Creative Cloud, Document Cloud, eLearning Suite, and Technical Communication Suite customers, we will be launching on September 9, 2019. For our Experience Cloud customers, we will be delivering your new experience later this year.
Between August 22nd through the launch date of September 9th, we will be transitioning our Creative Cloud, Document Cloud, eLearning Suite, and Technical Communication Suite community experience. During this time, we wanted you to be aware that all new threads posted and replies to existing posts in these forums will, unfortunately, be lost.
We apologize for the disruption but appreciate your patience as we prepare to bring you a fresh and engaging community experience.
-Adobe Forums Team
wait and see …
