So I have been informed that the 'comments' are all included within the framework, so this is an extension of a previous request that was fulfilled (thank you), but is missing the other half.
I would like to set a maximum edit time for comments (and replies). I find when someone has an unlimited edit time, it is easily abused. It's not good if today their comment (or reply) is about "X" and 3 months from now they edit their comment (or reply) to add spam. Just as it is no good if they have 1,000 comments (or replies) and later decide to go on a mass delete spree.
