UPDATE: Going forward, we allow for 15 MINUTES to edit one’s post. Here is why:
We allow a brief period for editing so that typos can be fixed and there’s a chance to complete a partial post that was submitted accidentally. We limit the time editing is available so that a member can’t change the content of a post after other members have replied to it. It’s not common, but in communities with a long edit window we’ve seen members completely change what they posted, which in turn makes the replies from other members look wrong or nonsensical.
