I made this for those sites that force you to register to view content. The mailinator home page gives you a random inbox, but selecting it is kind of annoying, and some sites complain about things like using the same first name, last name, username, and/or password. This will give you all the details you need in easy-to-copy-and-paste format.

It generates the password based on the end of the md5 hash of the username, limited to whatever password requirements you give it. Nice for sites that force digits or upper case letters. It also means you can find the password in the future if you need it by recalculating the md5 hash yourself. If you find out the requirements after putting in the other info you can change the parameters without it updating new random info.

There is also a checkbox to add a random 3 digit number to the end of the usernames. This is nice for sites where every username is taken. I tested the gmail registration and every single combo given was taken, none of the ones with random numbers were though.

It also gives an alternative domain to use if mailinator.com is blocked. If the alternative is blocked as well it lets you get another one without changing all the other info.
