You do not need agreements on the forum,
Need to review nominations and/or and submit yours, add photos, etc:
Where “Agreement (Reviewing)” means that when you review a nomination and decide to accept a good candidate, and the community also accepts it, you get +1 agreement. Likewise, if you review a nomination that is clearly bad and reject it, and the community rejects it as well, that is another +1 agreement. However, you do not need to agree with other reviewers on 100% of nominations. I think reviewers typically agree on about 60–70% of cases. The rest fall into a grey area where reviewers apply their experience and common sense differently.
