We constantly update our list of directories every 2-3 weeks to include newer directories. Whenever this update is made, you will receive an email from Directory Maximizer informing you of the update. Alternatively, you could login every couple of weeks to check for the same. Once you're logged in to your account, you could go to the 'Submit your Sites' section and below each site displayed, the number of unique submissions you can make is mentioned in brackets.
