In the moderator tools, is there a way for me to indicate that I've addressed a flag without flagging the post myself or marking the flag as invalid? For example, in one post, someone (I presume the OP) asked for clarification as to why the post was put on hold. I answered in a comment, but the flag is still left in the queue. I don't want to mark the flag as invalid, because it wasn't an erroneous flag, but I don't have any reason to flag the post myself either, and that appears to be my only other option.
After thinking about this more, I can understand why this isn't a feature (if it truly isn't) because it would mean someone besides a moderator could have the final say on a flag, which probably isn't the intent.
