I am trying to include add gadget by URL on a Google Site page. This is the URL gadget template I am trying to include: [login to view URL]
It seems that features in the gadget are not fully working. For example if you enter items in the template and a user subscribes on the Site, the user gets an email every update that is done to the site/page. However; when the user clicks unsubscribe on the email received, it does not work.
Please let me know if this gadget can be fully functional and if so, please advise time and cost to complete.
