A friendly warning about JavaOne submissions
As I (and many others) have mentioned earlier, the JavaOne call for papers is open.
But beware of the dog, I mean the submit button - this year the system has changed and once you click "Submit - Finalize" your submission is final.
Although this seems obvious for a "newbie" submitter, it is not for people that have submitted proposals in the previous years, as the old system allowed you to edit the submissions. In fact, you never actually finalized a submission, you could edit it until the last day. So I think they changed the system to speed up the selection process - once the submission is finalized, the Program Comittee could start evaluating it, without waiting for the final day.
I personally preferred the old system, specially when you have co-speakers and/or peers helping to review your submission. So, if you like this approach too, be careful and do these steps externally to the system, *before* submitting your proposal - once they're submitted, they're done.
