you can find links to all moderators in my sig
a contact us link at the bottom of every page(this goes to Ben only)
or PM a mod(probably better a super mod,those who have names in yellow)
or use the report button on any post
and remember there is a feedback system in the classifieds
But as I keep saying, it's best if you just fill in a negative rep on the system. Then an alert is sent to everyone, plus it helps people in the future.
There is a big "Leave Feedback" button next to the username on every ad in the classifieds.
its a bit off though having to use that, on ebay you enter a dispute with ebay staff first and see if its resolved before leaving feedback, surely that would be fairer stuff dont arrive member contacts staff staff contact other member, if they have already been given a bad feedback score they might think feck it no point trying to sort it now
