There are a couple of housekeeping things for the site.
First, tonight (or tomorrow morning) from 3-5AM Eastern, the whole network will be down for scheduled maintenance. We are moving our servers. So no worries if you can't access the site during that time.
Second of all, some big news for users. You now have the option to make a one-time change to your username, for whatever reason. No longer do you have to email support.
