I tried to get SSL cert for my fathers company and different kinds of certificates just scared me. Do you know there is a kind of cert where you need to go in person with your ID and register yourself? I'm currently using LE for 6 domains, 2 of them joined as first 100 LE domains, before LE was supported by Ubuntu.
