Richard and Thomas (Waldmann) have moved our wiki over the weekend.
The TLS certificate is a remaining problem, which are are still solving.

I've also rectified the user names of two users and
send an email to our users list.

== Details DNS problem
To be able to use letsencrypt, we either need to move the DNS hosting
for waldman-edv or they have to change their infrastructure to use a
different letsencrypt protocol (http now it is dynamic DNS updates).

Questions to Richard and Waldmann-EDV about preferances and possibile
costs are pending. Intevation is willing to sponsor.
