Edit: I've now added pricing to the front page of the site, in the currency (USD/EUR/GBP) matching your IP location. I've also added certificate length too.

Hi there and thanks for the feedback!

You can enter as many server names as you like.

Wildcards aren't possible with EV certs - both of these are mentioned on the 'Server names' box. The feedback is appreciated though so I may make this information more prominent if I hear this repeatedly.

I'm currently looking into the bug you found - it hasn't shown up in testing. What browser/OS are you using?
