Sorry for the downtime earlier... it seems we had some sort of mini-DDoS attack on the server but the attacker has now been blocked.
But I'm still finding posting on MW slow, and that includes opening and sending PMs and accessing the website. It's been like this for about three days now. I never said anything earlier because I'm having some minor computer problems, so assumed it was due to that. It does seem to be intermittent though and doesn't seem to be related to any particular time of the day or night.
