Hi,
I saw this and was thinking...
If the only reason a subdomain.mydomain.com structure is not possible because of the joomla cookie, then would it be possible to create the webpages outside of Joomla?
For example;
1) User subscribes to Joomla site, say "mysite.com"
2) Specifies page name, say "seeme"
3) Joomla component then creates a folder called called
www.mysite.com/seeme/index.html
4) User edits homepage etc - the Joomla system updates index.html under /seeme/ folder - extra pages created etc
When user wishes to "show" their site their describe it as
www.seeme.mysite.com which uses the redirection method used here (or whatever modification is required).
In this sense, Joomla is the "editor" and the "content" remains standalone outside of Joomla.
Your thoughts?
