You may be seeing a Cloudflare browser check message as you login and the site may be loading slowly for you. This is temporary and we're sorry about the inconvenience. The server that houses this site has been slowed down as the result of a DDoS attack and we are still under attack. A Distributed Denial of Service attack is deliberately malicious and caused when a lot of computers try to access the site at the same time - they place too much demand on the server and it locks up.
To defend from continuing DDoS attacks we are using a service to block malicious inquiries (from individuals, mostly overseas computers) from getting to the web servers. The screen and posting delays are because we have added this extra layer of security, verifying viewing to remove/stop malicious activity. This extra check is especially tough on those with slow connections and some mobile users but it cannot be avoided. Your individual computers and devices are not at risk and the site hasn't actually been hacked - just slowed down. You may see the browser check screen from time to time as your IP is verified.
