//now we will add what is called a select box. This is where users select from a drop down list. We will have two sample species called dragon and cat, but you can add however many you want.
//a select box works like this: the $_POST variable on the next page will be the name of the select box
print "<br><select name='formSpecies'>";
//but the value will be assigned to each OPTION
print "<option value='cat'>I Want A Cat</option>";

Pets as avatars
I'm hating hotmail right now, gmail keeps failing everytime it tries to send it. This code is from about 4 years ago, when there was forum up called the virtual pet project. Not sure if anyone is familiar with that but it was available for download, however the file download times out a lot and when you finally get it, it takes a little work trying to install it. The last comment on the forum was from like 3 years ago I believe...
