A great tutorial!

I had two issues, that others might also run into:

* you might have to execute the querys from step 2 manually (as i followed all the steps here to create the product, and didn't acually "install" it via the import product button)

* If you want to create a plugin that changes the template (instead of manually inserting the code into the template modifyoptionslike in step 4) you have to do some extra things - explained in this thread

Very Good Article

I have a side question, I know it says no help will be provided. But I want to have an option like "Enable Override" and then my options would override the usergroup options. For instance, if enable override is on and voting is off, the user can't vote whether they have usergroup permissions or not. If the voting is on then they can vote whether they have usergroup permissions or not. This way I can allow certain users to vote even if their usergroup doesn't allow it, or deny them access to vote even if their usergroup allows it.

Fantastic article. Any chance of doing something similar with vb4.x? Has it even changed much?
