Hi Erik,
I'd be interested in helping out for cl.net administration (I could only take over the day-to-day administration, though). But honestly, for me this would be a learning process - I have never been an administrator (so maybe not your best choice :). In practice, this would probably mean that I'll need a little bit of your supervision for the starting period. You are mentioning the shell scripts that are ready - is there a little bit of documentation for them? Could you say how much time this day-to-day administration usually takes?
Let me know what you think - maybe you just want to wait, if there are more people applying.
Best, Kilian
