Having a bit of a conceptual problem with templates.

Namely here are some questions and maybe someone has some time who understands it all :)

- you have your LSQL portal page - say home.html and you want on this page to make a link that loads a LSQL template of your choice - say you want a link to a subpage called 'Links Directory' and links directory is a template that will have available to it variables to pull categories and/or links from one of your top level categories. Can this be done without using a custom global in such a way that when the page loads statically, this link is hard-coded?

- How does LSQL know what environment variables are available to a page in question? E.g. category or link related variables?

- Suppose I just have an ordinary HTML page that appears to be outside the LSQL system - how can I make this page so that I can add LSQL tags to it and access system data on it?

Thanks
