Thanks very much Ken.
Yeah, I like the contactLP script for the general comments, but I want to create an easier user experience for the sign-up page I'm building, especially on mobile devices, so Google reCaptcha it is. I'll just have to root out the spambot submissions as they show up. I have a not-so-bad .htaccess block list going, so that should help.
Really appreciate the help and advice. Have a good weekend.
