Welcome to Revival. The forums is an important aspect of joining the Community. This is where you can meet other community members, apply for staff, provide suggestions and participate in many other activities.
I propose that the forum rules are edited so that people can leave comments on suggestions that are not +1/0/-1, As long as the comment they leave pertains to the suggestion.
We did this once and it bit us in the ass, never again.
At some point or another, there will be comments that do not pertain to the suggestion.
The current rule stands.
