There is one other way of sharing your page that you haven't seen yet and that's via secret URLs.
Secret URLs are a quick and easy way of giving access to your page to people who aren't already members of the Mahara site. The URL is simply a link to the page, which you can set up as a hyperlink and send via e-mail for others to open. The URL that is created is difficult to guess so that the general public can't easily find your page. Don't share this secret link via standard web pages otherwise it is likely to be found by Google and other search engines, and then it won't be so secret!
