Hi Patrick, I would prefer to have the preview on a separate page, so that if the object is validated, the user is sent to the preview page, and it it is not, the user is sent back to the form by using "render :action => 'new'", which will display the form + errors. On the preview page, there would be a choice to continue and agree to terms and conditions or to edit the post. The easiest way I see to do this is to actually create the post, and then if the user does not press continue or agree to the terms and conditions, delete the posting from the database. However, this would require a lot of unnecessary calls to the database (if there is a way to store and pass a temporary object), and would also cause posting id numbers to not be consecutive (say, if a user does not commit to the post.) I'm tempted to go with this approach because it is the easiest, however the inefficiency of this approach scares me.
