Sorry, friends: it's not working and I think I might have messed-up by including a trailing slash on the two URLs. The wiki certainly exists (https://rrf.miraheze.org/wiki/Main_Page works fine), but if you click "Wiki URL: https://rrf.miraheze.org/" (Description, above) you get sent to https://with.cpt-ra.bid//wiki/Main_Page instead (NB: two slashes), and therefore encounter "404 Wiki not Found". Apologies, -J
