I guess this is more of an HTMl - PHP question, kind of embarrassing that I don't know it, but I am a marketer not a coder, still learning.
There is a form on the right side of this page: new.320southwine.com beneath the slider. I want the submission to do a few things:
1. make sure the email address is in the proper format
2. take the submission and add the email address as a wordpress subscriber
3. send the user to a thanks we'll be in touch custom page I wil create
if there is a plugin you can recommend that will match my css then I will consider, but I figured it should be just some simple code to send. The tricky part may be the addition to wordpress subscriber no?
