Hi Matthias, glad to here that you working on it, because it starts te be very annoying. I'll also volunteer to clean all database for crags that I climb very often and know very well. Maybe you can you give 'super member' status to some people sorting by crag, based on number of ascents and reliability, and validated first by a 8a admin ?!
Bumping this. Some level of permissions above standard member but below full admin would be awesome for trusted climbers within given areas (especially those who are very particular about name spellings and duplicate entries, such as myself). I'd be more than happy to spend many hours cleaning up the crags I know super well if I had the ability to edit names and crag/sector details, as well as the ability to merge duplicates.
This is really annoying. Please give access to user to clean all this !
