In order to determine community consensus, editors can raise issues at appropriate community forums, [notes 7] or seek outside input through third opinion requests or by initiating a more general community discussion known as a request for comment.
If two organisms are closely related, their DNA will be very similar. Find something that can be improved and make it better—for example, spelling, grammar, rewriting for readability, adding content, or removing non-constructive edits.
