Real developers are not used to clicking, it's allways easier to write a script to do it for you.

Wow, thanks a lot!!

You Cadillac of men!

The only truly functional method. I will create a local script for the API, however this is great thank you for contributing!

Quick and dirty in the browser is so much easier than trying to use the API for a handful of domains.

Nice

thanks
