You should first browse the Frequently Asked Questions to see if your problem is already covered.
If not, you may submit a FAQ yourself and hope some other user will add the answer.
You can contact the web manager or browse our discussion forum.
You can also try to join us for a live chat on our IRC channel: irc://freenode/qurope. If you don't have an IRC client, try the freenode web interface (enter an arbitrary nickname and #qurope
as channel).
