Thanks! I have moved deep.ch to Supported list.
@matttap Thanks for supporting Lets Encrypt! I have taken the time to add you to the list.
@Spork_Schivago You didn't have to, you can generate the certs offsite via Linux live cd and just import then via SSL certs. There is a post about it with steps, its pretty simple. Bug them to support Let's Encrypt so you don't have to worry about it in future. Doubt they will care enough, but worth a try.
To everyone else, I have directly linked ALL sites which are supporting it. I have also VERIFIED ALL link proof and removed sites that shouldn't be on the supported list.
Do not add useless sites to the list to promote your site, I will move you to trash list aka not supported and remove links. I check the wiki often.
