Submitting to DMOZ is an artform. Whole companies have sprung up to deal with submissions.

As an ex-editor I can tell you that submissions can take up to two years to be accepted or rejected.

You are well within your rights to re-submit after twelve months, although resubmitting often will only alienate the editor and likely get you binned before you start.
