 * When I use the reCaptcha field I get the error
    Input error: k: Format of site
   key was invalid and I seem to remember that I have to get a site key from their
   site, but I have found no info on how to do that and where to enter that in the
   Custom Form setup. Could someone please give me some hints – thanks! Cheers, 
   Merlin
