You can't. What you may do is to decide what the one, best category for your site is, and,
in your original thread, either
(1) Ask if your site was submitted there. If it isn't you may be asked to resubmit. Continue with step (2)
(2) Submit the site to that category. After one month, you may then ask if it was received.
In any case,
6 months after a status report stating the site was found, you may ask again
in the same thread.
