Add Crag Chat

I realized that not all information that are interesting to share considering crags fit into the crag description section. Recently we went to a bouldering crag that was entirely overgrown and barely reachable. It needs proper cleaning. This information is interesting as you can't climb many of the routes at the moment, but does not fit to a general crag description. Maybe you could add a crag chat option where people can share recent information about the crag ?
