I've noticed some members have changed their username. Is that just me, or a new feature has been introduced to make this possible?
Nah, only Dan can change them - a lot of people have been asking. Heather, Raven and Sapphire have changed them so far.
Yeah, you have to ask me to change it. While you can change it through me for now, it's not recommended simply because it can really confuse people as to who you are.
