That’s up to the user I suppose. There’s nothing to stop any contributor posting - or pasting their activation report as an article on the summit pages. In fact many do. Furthermore, I note some participants ONLY submit their activation reports to these pages, and bypass the reflector completely.
I post my reports to the reflector initially, then (eventually) onto my personal website along with the photos and other information, and finally I post a link to the relevant webpage on the summit info page.
So the facility is there for that to happen, but it is up to the poster of the reports exactly how/where they wish them to appear. Even if reports are not posted or pasted to the summit pages, they can still be found using the reflector search facility, by any keen researcher.
All the same, there is something appealing about your suggestion for the contributor to be able to tag a post with a summit reference for future lookup.
