 Criteria
 --------
@@ -85,8 +85,9 @@
 
 Anyone who feels they meet these criteria can nominate themselves, or may be nominated by a third party such as an existing LLVM Security Group member. The nomination should state whether the nominee is nominated as an individual, researcher, or as a vendor contact. It should clearly describe the grounds for nomination.
 
-*FUTURE*: where nomination occurs (mailing list, GitHub, etc), can be decided later. See `Discussion Medium`_ below.
+For the moment, nominations are generally proposed, discussed, and voted on using Phabricator. An `example nomination is available here`_. The use of Phabricator helps keep membership discussions open, transparent, and easily accessible to LLVM developers in many ways. If, for any reason, a fully-world-readable nomination seems inappropriate, you may `open a new issue`_, and a discussion can be had about the best way to approach nomination, given the constraints that individuals are under.
 
+Our recommended method of nomination may change as our `Discussion Medium`_ story evolves over time.
