Sometime author needs to delete his/her project very soon after problem is solved to free space and the entire topic becomes obsolete for a reader. Can you copy such projects in archiive automatically to keep it forever?

You can ask authors for a permission to do that and let him/her manage the visibility later, yet putting projects out of limited private storages itself will help future forum visitors big time.

I've created a couple of interesting examples for forum, it would be pity to delete them cause my project space is limited with 12 items only.
