How many communities out there uses a "Feedback & Suggestions" -forum to handle feedback regarding your site and suggestions? This suggestion would make your feedback forum much easier to manage and aswell as easier to see which support-topics that has been solved(and not just locked - big difference).
I agree.
Aswell as an option to write an "about" snippet on each staff member.
I'm sure a lot of people want that since it's kinda general. This information could perhaps be fetched from the staffmember's "about" tab from the profile. Or a completely seperate thing.
This idea can be achieved with soft-delete.
Only allow your moderators to soft-delete.
That way you can easially see which threads has deleted items in them and at the same time be able to review and revert, if neccessary, the post(s)/thread(s).
