Category talk:Collaborative projects
I think this area needs two sorts of content:
1. The projects e.g. Geological walks of the UK, where contributors supply content on a theme, and
2. An area for the contributor to arrange content pertaining to the contributor/contributors viewpoint e.g like the Edinburgh Geological Society pages where there is a page about the Society and then page for each source guidebook.
This split is particularly valuable for legacy content e.g. the walks go under the main section and in the regional categories without any baggage about where the content was derived. The EGS page can provide a page for each source guide book - with a link to the individual walks.
