[Zope] setting flags

I've just installed a Zope message board and am trying to get it working but get 'Resource not found' errors when trying to add a msg. I think the security is set up correctly, but the problem may be due to the 'integrated' flag not being set to 1... index_html says:- If you want to integrate MessageBoard in your product you must set 'integrated' flag to 1. How/where do I set it to 1? I realise this will probably be in the Zope docs somewhere but have no idea what I should look for. -- John
