Currently, Crucible allows users to resolve comments authored by other users. I consider this a bit inconvenient: in contrast to JIRA, the resolved comment stops blocking the review immediately and you can easily forget to pay attention on the fact of the resolution. The email notification is not enough too, it can be missed easily in tons of other emails from Crucible. As a result, code with defects can mistakenly be approved on review.

In our workflow users shouldn't resolve comments not authored by them, but they do it sometimes by mistake, since this rule is not required by the Crucible permission scheme.

Suggestion: add "Only author of a comment can resolve it" checkbox to the permission scheme page.
