As many of you may know, I am leaving my position at Hothouse Magazines to take up a new career opportunity at Puddinghead Publishing. My last day of employment here will be 14 March 2010.
I wanted to take this opportunity to express my thanks to all of you who have made my time here such a great experience on both a professional and personal level. Thanks for all the support and guidance – I have learned so much and will really miss working with you.
I would love to keep in touch, so please feel free to contact me at email@example.com.
