I can answer two of your questions......
You can also use the external page syntax to create absolute links to wiki pages:
- [https://yourdomain.com/Page+Name] (assuming you're using SEFURL)
Similarly, you can use the external link syntax to link to trackers, file gallery objects, etc.
That's not a satisfactory solution... It makes the links dependant on the host on which the wiki is running.
Yes, I know that page. It doesn't say anything about namespaces, or relative and absolute links.
Thanks for your answer.
