I need to generate a list of active node types for a site, and I'm not sure how to go about doing that.  What I need is an array something like this:

$ntypes = array('blog','forum','flexi','page','story')

The end result would be a list of possible node types a person would be able to subscribe to using the Subscriptions module.

Any ideas how I might be able to find out which nodes are available for subscription?
