Welcome to ExHelferNet, the Schloß Elmau ex-Helfer(in) Network.
This is the fourth incarnation of the site (a simple update of the first Google Sites exHelferNet, which followed exElmau), designed to allow anyone interested to update the info rather than relying on one individual to keep track of everything. Any former Helfer or Helferin can suggest and even implement changes to the site.
Wikipedia has some general information on Schloß Elmau itself (and of course the Schloß has its own website). This site is here for those who used to work there as Helfer or Helferinnen, to enable them to reminisce and maybe get back in touch with old friends.
As technology and capacities have progressed, the site has been simplified to one big shared spreadsheet with over 200 names, hopefully making it more usable and easier to update.
Some other sites which may be of interest:
There are dozens of pictures on Marco Schipper's site.
Dozens of photos of Elmau in 1980-85 were on Flickr, but were deleted when it stopped free storage. Maybe they'll find a new home sometime in the future...
The Yahoo Group is likewise defunct - it wavered between frenetic activity and months without a single message, but was a very good way to find old friends. Here is an archive copy.
The Dutch "Hyve" is also defunct - here is an archive copy.
The most active group now, particularly for more recent Helfer/Helferin, is on Facebook.
Much of the various lists is based on the memories of the founder (Ben Jones), and his correspondence with others in the years since. The site used to include email addresses, but these changed often and have been removed. In theory, those listed here will update their own details, but few do, and most people searching for old friends now tend to use social media instead. Those who have since married are shown with maiden names. If you see someone you'd like to contact but no details are shown, try searching on Facebook or LinkedIn, or asking in the FB group. To add names (or dates) currently missing, or update your own info, contact me (via ozaru.net or FB/LinkedIn) and I'll share access so you can then edit the site yourself.
