We do not give any form of site status check.
As the FAQ indicates, the wait period for a volunteer editor to consider your suggestion can easily be measured in years.
If you have suggested your site to the single best category, and have read the guidelines and believe the site qualifies for a listing, then all you can do is wait. There is no interactive communication during the process.
There is also absolutely no reason for the wait to be painful. Either we will list it or we will not. since no one can control the timeframe, and the window of oppotunity can easily be measured in years, then one should follow our standard advice: suggest it and then forget it.
