I don't like the idea of walking away and leaving my account live.In any event, it would seem that with only 3 posts (all in this thread) that walking away and not looking back would be the simplest solution.
I don't care that the site might retain the words I've posted but leaving a live account (linked to my email address) is very poor security practice.
As for waiting for the Admin to develop the process to cancel accounts - I would have expected that function to have been put in place on day-0 ie creation and deletion of user accounts.
