Templates.

In this Pinned Link: http://www.asprunner.com/forums/index.php?showtopic=9692
There is a point that mentions Template Merges:

- Templates Merge

Create a new project using two templates or add a template to existing project
How does one go about using multiple Templates in the samge project. I've tried, but as a newbie it escapes me.
Thank you.
