Email Digest and Activity Story GUIDs

Yes I would also be interested in this, in the latest build of v12 the defaults are 

aba4d84614b9464f8318793d8a963fe1; 0a680cf3f19648c592dbdf8cebe3fe92; 948477cb045b40778bf17ce1a091db11; 333cc77c019644c5aefa6e35a0011ee8; cf26068cf6644050bf69f1d5c3e7eb1a

Converted by using 

IEnumerable<IActivityStoryType> activityStoryTypes = Telligent.Evolution.Extensibility.Version1.PluginManager.Get<IActivityStoryType>().OrderBy(x => x.StoryTypeName);

You can get information on enabled Activity Story Types by entering the following in a Studio Script Sandbox like Widget Studio's:

#set($apiListResponse = $core_v2_activityStory.ListActivityStoryTypes())
$apiListResponse

You can drill down into the result object to find the desired story type ids.

You can manage story type enablement at Admnistration > Activity Stream > Activity Story Types.

Do these change version to version? This seems like it would be prime Article material to just run with all of the types enabled and document as a quick lookup.

The Ids will never change, only potential new ones be added.

We do have a related ticket logged that would improve this selection process:
