Hello,

First, make sure your application would actually be approved and is not considered junk by SlideME: http://slideme.org/faq/developers/what-is-the-application-approval-process
Whether you consider it to be a useful application or not is irrelevant to the review process.

Secondly, ensure you check the box in the edit node that says "Published". If you do not check this box and leave it unpublished, it will never be reviewed.

Finally, if your application status does not change after 4 days from checking the box "Published", please use the contact form to open a ticket and include the URL of your application on SlideME.
