I have been watching the ACME development for some time, and I finally jumped on in early spring and got all my STARTSSL certs replaced with Let’s Encrypt–thanks!
Another tip-of-the-hat to the Let’s Encrypt and ACME developers–GREAT WORK!!
The process works great, but the clients I tried weren’t completely satisfactory for my server set-up. However, I’ve now found the perfect client for me:
