Appendix A. K2 blackpearl Tips and Tricks

When we started this book, we wanted to make sure that everyone who read it came away with some good information, not only from the information contained within each chapter but also from the insight each author provides. That in great part explains why the authors were chosen to participate. They come from a variety of fields and have a variety of experiences that should help you take advantage of the K2 platform. To further this idea we have collected various tips, tricks, and "how-to" information from a broader audience, including K2 employees from around the world and community representatives who have discovered some great time-saving techniques. Some of these things you may have seen before on various K2 blogs. Others will be new. We hope you find many of them useful.
