it depends. some groups may choose to start cobing immediately on bid day. some may wait for a few days...or a week before hosting parties. some may even initiate the newest members and then host cob later in the semester. some may just wait until the spring. i wouldn't worry too much if you haven't been contacted yet. it is great that you were able to get your name to the greek office, but definately keep your eyes open for postings around campus. you may also want to mention to your friends who are in sororities that you did sign up for cob. they may be able to tell you when groups on your campus are hosting parties.
