Cancel or Replace submission

I just submitted my site, but now that I think of it, my listing didn't exactly follow the guidelines and my site isn't quite ready. Is there a way for me to cancel or replace my submission?

No. The listing can be fixed (editors expect to have to do that) and ... spend the next month getting your site ready. Then you can ask about the status of the submittal. If already rejected, wait until it's ready before resubmitting. If not, no problem this time (just don't do it again, you can get a reputation that way.)

I think what I'm concerned about is that my title is too wordy and my description is to vague. But yeah, I'll wait for an editor to respond to see what needs to be changed.
