I am moving on

Hi everyone,

this year I have moved to a new role and do not have to do as much with Thin Clients anymore are I had in the past.
Therefore, it is getting harder to help you all in the forum and stay up-to-date with all the news.

I really do not want to kill this site completely. However, if anyone out there wants to take care of this site, let me know at confgen (at)

Best regards
