Activity for Justin

I will be officiating a wedding for friends soon. I am in California and I understand that I don't have to register or anything like that. But is the site legit? I've been referred to "Universal Life Church" but www.ulc.org and www.themonastery.org...

I've looked on the internet and read up on the laws in the state and it seems pretty simple to do in California. It also seems really easy to get ordained online. Has anyone done this? Are there any free, legitimate non-denominational websites...
