+## Looking for new maintainer(s)
+
+As much as I love ruby, grape and AMS, I am no longer using them. I think that it makes sense for someone else to pick this project up as a maintainer so that it can be kept more current as I feel I have been neglecting it. If you want to maintain this project, please email me at contact@jrhe.co.uk. I will continue to merge changes in when I have time. Cheers - JRHE
