Tammie Lister is a designer and theme developer. She's passionate about community design and mixing in psychology with design and development to create these communities. She is lucky enough to create a wide range of communities with her clients. Her background is both in design and development. She has worked as a freelancer for over 10 years from her own company called logicalbinary.com. She has spoken about BuddyPress and communities at WordCamps, BuddyCamps, and other conferences. Her contributions to BuddyPress include being part of the community theme for BuddyPress, UI, and a new template pack. She also has a sketchbook where she explores and experiments with BuddyPress at buddydesignlabs.com. Special thanks goes to the editorial team that made this book happen. A large thank you goes out to Alison Barrett, Brian Messenlehner, and Paul Gibbs, who gave their time as technical reviewers. This book is dedicated to the core team behind BuddyPress for all their work. A huge thanks also goes out to everyone that contributed in any way in the project. BuddyPress is made up of the people involved so thank you. I'd also like to thank my editors and reviewers for helping make this book the best it could be. Last but not least a thank you goes to my husband Simon for understanding my passion for writing this book and open source projects.
