looking for someone who just got this game & hasn't played co-op yet

[Murphy's Lawyer]

WIth Portal 2 on sale this week, i figured I'd post here to see if anyone who hasn't played portal 2 yet buys it this week would be interested in doing a little co-op together.

I need to play co-op with someone who has never played co-op before to get the "professor portal" achievement.

IF anyone is available to do this, let me know
