A small award should be arranged for them. For this, everyone will be encouraged to post better. And the forum will improve further.
With or without an award, you are encouraged to post the best that you can come up with. With or without being a part of a signature campaign, we are guided by the forum and ethics as a member, and besides, we already have the merit system that will help you rank up and gain a reputation, so I think we don't need these awards.
