You'll know it has been accepted when it is listed in the category on the public side.
Some sites get moved to a different category, that's when it may disappear from the submitter's view, whilst actually being published. You can use the ODP search to look for it, but note that it will find it only after the next RDF dump after the site has been added to the public side.
If you haven't seen any movement in at least 4 to 6 weeks or so, ask again in this thread for an update. It may take a long time to be listed, or someone may do it tomorrow.
