(One solution is to also add an encrypted timestamp form field which CF can then decrypt and check it is within a certain limit, bearing in mind that you need to cater for connection/transfer time and page rendering time, so you may need to set it to five or ten seconds above your JS limit, if it's potentially used by slow people... uh, people on slow machines/connections, that is) -- Peter >LOL!
