evaluation questions

Hi,
I am evaluating Lenya for usage in a small project and I have a few
questions about it's capabilities. First question is about a valid demo
site, as it seems that the existing ones are not working.
Also, is there a way to create a page from different sub-components in a
template?
And the last initial question, is there support for scheduling a page going
in and out of live mode?
Thanks in advance.
Eugen.
