"mailto" not working
Most likely, if using gmail, with your code up to snuff, and your 'mailto" link isn't working, you'll need to set your email default client.
~ Open your gmail, click the protocol handler icon (see arrow in Fig.1) Looks like double overlapped diamonds
! If you don't see the above "protocol handler" icon, then just skip to"Step 3"
~ Under "allow Gmail to open all links?"; select "Use Gmail",
~ Click "Done",
~ and there you are, success. Your "mailto", should be good to go .
! If you don't have the icon, Step 3So hopefully this worked for you, now onto bigger and better,
~ To Your Success
