go ahead and complete the code set, when it's ready to check in, do an sqlCVS update of the DCE and IR repositories, using the sqlCVS menu in Web Admin...
after you've done this, make sure your template is okay, then:
Go to http://svn.linuxmce.org/
and make a trac ticket for your template.
use sqlCVS diff to check it in, leaving the credentials as anonymous.
reference the trac ticket # in the comment field. this is important, so we can track it down.
Once this is done, we will verify that it is okay, and approve it.
Once this is done, your template will be available to others, and can then be selected in the setup wizard.
