<a href="http://wiki.roll20.net" rel="nofollow">http://wiki.roll20.net</a> is inaccessible (looks like the wiki is only available over HTTPS), but since it's hosted by CloudFlare, it displays a CloudFlare error page that says the host is down instead of a generic connection error. Would you consider configuring Cloudflare to force HTTPS/rewrite HTTP urls to HTTPS urls for that domain so it would silently work for users instead of erroring? <a href="http://roll20.net" rel="nofollow">http://roll20.net</a> silently redirects to <a href="https://roll20.net" rel="nofollow">https://roll20.net</a> .
