What do you want to know?
Why a contact page instead of an actual email address that you can copy and paste into your email program? Because of SPAM. There are programs that scrub websites for email addresses and then send spam in large quantities. So one way to reduce this is by having this contact field that creates the email address. If I email you back, then you will have my email address. Feel free to ask a question or communicate with me, but it is also useful to post a comment under the information about which you want to communicate.
