How can I configure the Activity Feeds Wall in MS Dynamics CRM 2013?

Hi everyone,



I'm currently working with Microsoft Dynamics CRM 2013, and I would like to configure/customize the Activity Feeds Wall that we can find in default dashboards, but I don't really know how to achieve my goals.



- How can I add or remove entities in the "You follow" filter list?

- How can I add or remove entities (in particular custom entities) in the "Posts about" filter list, if I can't find them in the entity list of the "Post Configuration" section? I have only 29 entities available in the list (accounts, contacts...), but I can't find the custom entities I have created.

- Is it possible to add new rules in the "Post rules configuration" section? Or can we only use workflows to create and manage automatic plublications on the wall? I only have a read access for the records of the "Post rules configuration".

- Is it possible to add more options in posts? By default we have the "Like" option, but could we add other options like "Need" (for "I need this thing"), "In Stock" (for "I have it in my stock")...

- Do you know where I could find the web resource file "msdyn_/PersonalWall.htm" used in the dashboards to display the Activity Feeds Wall? And do you find it could be an idea to customize this file to get what I'm looking for?



Thanks a lot for your help and your answers.
