Numisdoc edit

I noticed that some articles from numisdoc are obsolete and I don't see any possibility to refresh the content. For example now we have a banner on the profile pages of those who are suspected to be swindlers and this information don't appear in "Swapping step-by-step" article and it might be useful for our new members. So know anyone if there is any way to refresh some content? I think it would be useful a button to edit the content and someone to validate.
