I have had several members troll my gallery here in the past, after forum or chat room disputes or whatever, and I think it would be nice if I had the power to remove those comments from my gallery, without having to consult a moderator. The comments don't really offend me - if anything, they make the people who leave them look like idiots - but it would be nice to have some control over the juvenile actions of others, when it comes to my gallery. Most other communities have this feature. Of course, it could be abused - people deleting genuine critiques because they only want to hear flowery praise, but I still think self-moderation in one's own gallery is a good idea.
