Mandrake, AKA Geoff Harrison, is a heavy contributor to the enlightenment project and has also left his mark on Gnome, XFree86, and a bunch of other excellent free software projects. In real life, he works for VA Research as (surprise!) a software developer. Mandrake is, without question, one of the leading lights of the Linux and free software development communities. Check his Web site, and post any question(s) you have for him below. Answers to most or all of the highest-moderated ones will be posted Friday.
