Hi Mark
No you will not be told. Apart from all the work involved, we never know whether the suggestor had anything to do with the site and it would only encourage 'arguements'.
You are the best person to see whether there is anything specific stopping your site being listable by checking through our
editing guidelines and the descriptions for the chosen category and (especially in commercial categories) all the categories above. After that the rule of thumb is to look at the sites in the chosen category and compare it with yours in terms of unique content.
If you are happy that it is probably listable, then probably it is sitting in unreviewed waiting.
regards
