The People Tree is a fair trade online fashion retailer (www.peopletree.co.uk).

Although I'm not a client of Propellernet, I find their insight invaluable. I read their newsletter every month and regularly check their blog, which helps keep my finger on the pulse of SEO and link development, and often sheds light on new developments that I haven't read elsewhere. As far as newsletters go, it's the only one I make time to read!
