In the meantime, we got visitor chairs and some other visitor:

In addition to a bicycle storage room for employees, there are also EV chargers. (Now, e1 is taking care of billing, but initially an RFID card from Bílahleðslan is needed -- they used the IT infrastructure from Everon and some of the involved registration emails are prone to be deleted by spam filters.
