It seems as though you already know how to implement the same form in multiple templates, but you've having trouble avoiding repetition in your code. To that end, here are some suggestions for reducing the amount of repetition you'll encounter when duplicating this form across multiple pages:

• Validate data within your form rather than your view. Currently, you are checking for duplicate e-mail addresses within views.py. If you duplicated your form, you'd have to re-write that code all over again. Instead, why not move it into forms.py in a custom cleaning method (see Django docs on custom form cleaning).

• Write functions for actions that will be repeated. For example, currently, you are sending an activation e-mail to your user within views.py. It makes more sense to write a function within your user/models.py called something like send_activation_email(). Whenever you want to send an activation e-mail to a user, you can then call user.send_activation_email() rather than duplicating your entire block of activation e-mail code (see Django docs on model methods).

• Use inclusion tags to avoid repetition in your templates. If there's a block of code that you find yourself repeating in your templates, you can use Django's inclusion tags to include a snippet of HTML across multiple templates. This allows you to serve the same form in multiple locations without re-writing your code. If you want to style your form differently across multiple pages, you could wrap it in DIVs with different IDs and use CSS to style the form differently depending on which DIV it's wrapped in.
