Thanks for alerting me to this Hilmar.
I am sorry that this has happened.
I have removed the offending material and changed the registration to
be by invitation - which is a shame but I guess it is the world we
live in.
I have raised your status to 'manager' so that you can delete stuff as
well.
If anyone else would like to be a manager please let me know and I'll
up your status too.
The approach I have taken to stop this happening in the future is
therefore to carry on allowing members to contribute to anything
(discussion, files, pages) but to have some level of vetting on who
becomes a member. No content is hidden from the public at large. I
will promote any member who seems trust worthy to being a manager if
they want to take on that responsibility.
Does this seem reasonable?
Roger
