Dear Bobrat,
In response to your question .... "If you could tell me why you expect to hear something it would be appreciated. A lot of people seem to ask this question, and anything that can be done to stop giving the impression that ODP notifies anyone about reviews would be helpful".
The instructions for "How to submit a site to the open directory" states:
Procedure After Your Site is Submitted
An ODP editor will review your submission to determine whether to include it in the directory. Depending on factors such as the volume of submissions to the particular category, it may take several weeks or more before your submission is reviewed.
Maybe if this was changed to read "two hours or two years or more"....as many of you point out....no one would look for their site to be listed in one month.
You may want to also clearly state "You will NOT be notified by email if your site is listed, reviewed, not reviewed or rejected".
Maybe this would help with all of the "status checks" and people wondering why they haven't "heard anything from you".
