Add an FAQ entry to explain why somebody doesn't appear on a project's "Who" page. The short version is that:
They must be elected
The Election must be complete
They must provide the required paperwork
The paperwork must be processed by the EMO Records Team
The webmaster must create the committer account
Each piece takes time. If a committer doesn't appear some number of days after the successful completion of a committer election, then contact the committer to confirm that they've followed the provided instructions and have submitted committer paperwork.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.
If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
