Update & Secret Key

Hi.

This is a very important plugin. Appreciate the time and effort. Would be great if it is kept updated.

I would like to know if it is possible to insert the key in the rss feed address? I am trying to retrive the secret rss feed into the mobile app that I am creating for my website.

Cheers
