When using Web Wiz Forum to support a user group for 10+ years (Danish LEGO User Grup "Byggepladen.dk", some of the links in posts, news etc. will eventually - and inevitable - go dead.
I would really like to see an administrator function to test all links for availability and perhaps even embed dead links in a proper message stating the original link and the fact that is seems to be dead.
As an option, the function could be scheduled (like once a month), use history and a threshold for links to "qualify" to be declared dead - and maybe even reviving dead links that have resurfaced.
