CPAnet is still going strong and will continue to do so. CPA Exam Club will just make it even better. You will see links here pointing to specific discussions/resources at the Forum and as you will notice there are direct links to the main forum areas at the top of the page here.
Yes, there will be a little information lost when there are scheduled chats, however, I will be looking for ways to create chat transcripts. Plus, I think it's beneficial for you all to interact via chat every once in a while. It can be a great community builder.
So never fear, the CPAnet Forum won't be going anywhere! ;-)
