From staff:

There may be a little downtime today...nothing to worry about.
Please do not send messages asking if it is down...I seriously will have a sense of humour failure and start hitting the delete button!
I have switched messanger off for the time being and will resume doing passwords as soon as we are back online

Update:

And we are back!
Password edits can carry on (don't forget your usernames!!!!!)
Please don't send messages saying that you couldn't get on to the site earlier....nor could I!!!
