Hi Tom,
nice website you've got there.
Yes, I'm logged in as administrator. Also had a long look at the Admin Guide, so I did really RTFM. The web & windows sharing services refuse to show up in the Sharing panel even after doing everything (?) by the book. I can't beleive I'm the only one with this problem, but there's no hint anywhere, these services are just taken for granted in every manual I've read.
