Hi Bob, we're still working out all of the history options. There will definitely be comment-level history, and we're working on models for conversation-level and/or wall-level history. Looking forward to input on what works best once it's live.

We also know it's important for people to be able to remove comments from their own message walls. Still figuring out if they should be held in public archives or not once removed. Thoughts?
