Challenge points
First thing I did when I noticed was change my password, log out and log back in.
I always use a unique, generated password for everything though. Certainly not easily guessable.
Some sort of session takeover?
I'd like to get the challenges I haven't done myself reset.
Any idea who the best person to contact is?
The reason I ask is because I pm'd mr_cheese regarding another matter to do with a challenge error where I got a message telling me to contact him and have yet to receive a response.
