Looks like a forum mirror set up to collect OSM user passwords.
Or an alternative URL for it. Lambertus?
Good afternoon!
It is or - rather was - the remains of an experiment to replace the forum-style with a mobile-enhanced version on the fly. The result was quite disillusioning (it worked, but the style wasn’t really better on mobile devices), so I removed everything except for the reverse proxy - which I simply forgot. Since then reidel.me simply proxied all requests to these forums. No passwords were collected - no harm done. I already removed the reverse proxy, so nothing remains of the experiment at all. Sorry for the inconvenience.
