Namespaces allow you to run mutliple 'sites' within 1 jotwiki.
You should edit at least the 'default' namespace to set your main site option such as title, URL etc...
You will want to create other namespaces if:
- You want to have multiple section of the sites with different looks and/or users.
- You want to run multiple sites with different host names in 1 instance of jotwiki.
Unless you want to do one of those two things, you should just have the "default" namespace.
The default namespace, is the one accessed when you simply go to http://hostname/ or http://hostname/default/
If you create a new namespace say "site2", you would access it at http://hostname/site2/
You could then map that (http://hostname/site2/) to a hostname such as http://www.site2.com/ using mod_proxy.
See the jotwiki site for more informations on doing this.
