Events in intro of group are sorted by creation date instead of event date
The order of articles is usually based on creation time. This follows the expectation of users in most situations.
In the specific corner case of events being marked as intro items of a group (i.e. a preview of future events organized by that group), a sorting by event date could be more suitable.
Of course, this is tricky, since it is hard to determine a proper in case of mixed article/event/something contributions. I am not sure, whether it would be good to use a different sort order in the very specific case of all intro items being events.
Opinions?
