I got this email some hours ago :↵

Title : Codeforces , From : Penny Zhang <[email protected]>↵

_Hello all,_↵
__↵
_If you're interested in exchanging solutions to Codeforces (and maybe even TopCoder) problems in-contest, reply to let me know and I'll explain the system in more detail. The main goal of the system is to prevent leeching (receiving solutions, but not giving), and to prevent detection (altering code). I'm expecting a final ring of size 4-8. I suggest you make a new email account for this to maintain anonymity; use a proxy if you want to take it a step farther. Ideally, no one in the ring should know a single other person._↵
__↵
_Quick note: This setup will not be ready by the next contest, which is in less than 12 hours. I hope to be ready for round 321 (in several days), though._↵
__↵
_Again, reply with "I'm interested" using an alternate email account (preferably), and I'll include you in a group email._↵
__↵
_Thank you all,_↵
