We use Contact Form 7 plugin on our church website. Currently the form requires an email address and validates it.
Some people may want to contact us that do not have an email address (they may access our website from the library, etc.). The ideal situation would be to have the email validated if something is entered in that field, but not require the field be filled in. I don't think that's possible, but it would be great if that were possible.
So I am considering removing the "required"/validation element. I want to leave the field for folks that do want to share their email address, but I don't want it to be "required".
Should I have any concerns about doing this such as security, etc.?
Also I'm sure I can find the validation PHP code to change it, but if anyone knows exactly where it is, that would be helpful.
