To share your theme with the URL, you need to mark your theme as public. To mark a theme as public, go to the theme from Mykuler after logging in. Then click on the 'make changes to this theme' button present on the top right of the theme description. You will see a radio button next to public on the top-right of the page(same as the theme creation page that now appears). Click that and save the theme by clicking the save button. The theme will then be accessible via the URL.
