Twiki setup help, please

[stan]

I'm trying to et up twiki to use as an internal "knowledge base" .
I want anyone to be able to read anything that is there. I would
like to have users have to "login" to create/edit content.

I've installed from the ports, and added the appropriate section
to Apaches httpd.conf. I've made certain that everything under 
/usr/local/www/twiki is owned by www, and group www. I've set up 
a link that points to twiki/bin/view/Main/WebHome.

Problem is that when I go to that link, it tells me that "Main
Web" does not exist. It offers to let me create it, and I get
form that I can fill in. But when I try to commit this web,
I'm told I don;t have permission to create it.

What am I doing wrong?
