At the moment, if you only want an ad to run for a maximum of 14 days, then you simply edit the template and remove all the other options. The problem is that Firefox comes with plugins, such as Web Developer Toolbar, which allow you to edit a drop down box, i.e. turn a drop down in to a free text box. On our installation of PP Classifieds I've added a routine to the php which hard codes acceptable expiry lengths so they can't be overridden. Can I suggest something like this is considered for the future? It just makes the software a little 'harder' and less prone to exploits. Thanks
PS. If anyone wants me to demonstrate how easy it is, or to demonstrate on their test installations, then just let me know.
