 A project lead may also retire a committer. A project lead might, for example, retire a committer that has been inactive for an extended period of time (e.g., longer than a year). Before retiring a committer, the project's community should be informed of the change and the committer must be given a chance to defend retaining their status via the project's dev-list. 
 
+Retired committers are listed as _Historic Committers_ on a project's _Who's Involved_ page. To restore an historic committer to committer status, they must be <<elections-committer,re-elected>> into the role.

 [NOTE]
 ====
 A common practice is for the project lead to use the project's dev-list to announce generically that they're going to retire committers that have been inactive for some designated period of time and give the committers a chance to speak up before a deadline.

+What is the difference between a _Committer_ and an _Historic Committer_? ::
+
+The _Who's Involved_ page lists committers and (in many cases) historic committers. Committers are those individuals who currently hold committer status (i.e., they can write to project resources). Historic committers are retired former committers. While they hold a special place in our hearts, they have no official status on the project. To turn an historic committer back into a committer, they must be <<elections-committer,re-elected>> to the project.
