Adobe Revel's presence in Premiere Elements 12/12.1 and 13/13.1 is found in the Elements Organizer as well as in the Editor Publish+Share/Private Web Album. Before Premiere Elements 14 was released in September, 2015, it was announced that Adobe Revel features were not to be included in 14, but Adobe Revel would still be available in Premiere Elements 12/12.1 and 13/13.1 as usual.
Today November 20, 2015, we have received the following email from the Adobe Revel Team, announcing that Adobe Revel will no longer be available after February 23, 2016.
Pending further information, we are left to assume that, when you open Premiere Elements 12/12.1 or 13/13.1 after February 23, 2016, Adobe Revel features will be unusable at the Elements Organizer or Publish+Share levels.
We are seeking more news on this specific to Premiere Elements 12/12.1 and 13/13.1 and the Adobe Revel features that came with the purchase of those products. Further news will be reported here as it develops.
A thread was posted in the Adobe Revel Forum, requesting clarification on Adobe Revel discontinuance and Premiere Elements 12/12.1 and 13/13.1, and a prompt response was obtained from GlenyseH (Adobe Staff). See thread found at https://forums.adobe.com/message/8198667#8198667
For convenience, the following is a copy/paste of the GlenyseH response.
Photoshop Elements 11, 12, and 13 all had integration with Revel. With Revel shutting down, your Elements app itself will still work but there will no longer be integration with Revel. That feature will be gone.
