I just became ordained so that I could marry my friends this summer.

I find this hysterical and slightly disturbing that all I had to do was fill out an online form.
A couple of questions...
1. If anyone has done this before...what did you have to do to register with the county?
2. Any suggestions on what makes a great ceremony beyond just having a few personal antedotes of the couple? We will not do anything faith-based in the ceremony, nor will there be any breaks for songs. We will do a unity candle or something like that. But beyond google searches I'm a bit lost as to what I should incorporate beyond the required "I do."
