dovecot - Oct 2014 - Public root folder is \Noselect

I am utilizing a public namespace via
http://wiki2.dovecot.org/SharedMailboxes/Public and using sdbox storage format.

How can I get rid of the \Noselect flag that is set by default for this folder?

IMAP output:


b LIST "" "*"
* LIST (\HasNoChildren \Sent) "/" Sent
* LIST (\HasNoChildren \Trash) "/" Trash
* LIST (\Noselect \HasNoChildren) "/" Public
* LIST (\HasNoChildren) "/" INBOX


If this is not possible, what is the best way to create a sub-folder in here
upon system setup (one w/o a \Noselect flag)?

Thanks,
G H
