Some of this will depend on whether or not you have a logged in area. I have added these systems in the past, but only with certain backend protections.
For instance, You can limit it to 1 email address per send Offer an 'opt out' link for the recipients to add their email address to. Add a time-delay, after they send 1 message, another can't be sent for 60 seconds. Load the form into a frame, if the page isn't called from your site, or have specific criteria that you select, don't allow it to be viewed or sent. There is quite a few things you can do, but just remember that the best solution is to make it a logged in area and track who is doing 'what' so that you can shut them down if need be. William Ps. You can't stop spammers, only slow them down or make it so difficult that they have to go somewhere else for their tricks. -- William E. Seiter Have you ever read a book that changed your life?

Has anyone solved this and made such a tag/module available? My site's users are demanding such a feature. I've never use the Send to Friend but to my surprise a lot of people do. I'm concerned that adding this feature will welcome spam bots as most send to friend features offer a Message Input box. Is there any safe way to go about adding such a feature? Are there any platforms out there that I can integrate with to avoid trouble (feedburner etc)?
