 Staffing is our dominant cost. We currently have eight full time employees, plus two full time staff that are employed by other entities (Mozilla and EFF). This includes five operations/sysadmin staff, three software developers, one communications and fundraising person, and an executive director.

 The Apache httpd ACME module is called mod_md. It’s currently in the [development version of httpd](https://svn.apache.org/viewvc/httpd/httpd/trunk/modules/md/) and a plan is being formulated to backport it to an httpd 2.4.x stable release. The mod_md code is also [available on GitHub](https://github.com/icing/mod_md).

 It’s also worth mentioning that the development version of Apache httpd now includes support for an [SSLPolicy directive](https://httpd.apache.org/docs/trunk/mod/mod_ssl.html#sslpolicy). Properly configuring TLS has traditionally involved making a large number of complex choices. With the SSLPolicy directive, admins simply select a modern, intermediate, or old TLS configuration, and sensible choices will be made for them.
