Hey Guys or Gals,
I have the everyone group and pseudonym disabled on my server. Every now and then it seems to become re-enabled. My guess has been that it happens when I add a new user but I don't really know if thats what causes it. My question is, does anyone know specifically what causes it to become re-enabled?
You most likely disabled it by editing the configuration files, which is a bad thing as they are regenerated on a lot of occassions (like user addition) from templates.
AFAIK every configuration file has a warning on the top not to edit them... why did you choose to do so. Do you think they are put there for fun?

You should make a copy of the original template section to the custom tree and modify the copy, reexpand the configuration file and start affected services (or reboot). More information on the template system is in the wiki, look for the SME Server Development Guide.
