Taking all your good advice into consideration, we've put together this form:
Contacte a GRUATEC en San José, Costa Rica
We don't know PHP so well. We copy code from here and there and then test it. How do I know for sure that spammers aren't going use this form to send spam to other people? What is it exactly that I have to enter in the fields to check it? I know it has to be something that uses slashes and other symbols, but I don't know exactly what.
Thank you for your help.
