This plugin is related to the acts_as_nested_set functionality but
in that it allows multiple roots to exist within your database.
The other benefit, is that when adding a child, it doesn’t perform a
table update to rebuild the tree, each child insertion only affects the
that it is placed in.
It even comes with my first screencast to show how you can build an old
school threaded forum.
Check it out if you need this extended functionality.
It’s certainly possible that acts_as_nested_set can be massaged to
this functionality, but I found it quicker and easier to build it
This is a 0.1 version and I haven’t created the unit tests for it yet.
Please send bug reports and feature requests back my way.
