I thought I'd nominate the Just got a Zoom H4 thread. Because many PW members are interested in recording their playing, and the Zoom is such an inexpensive, easy, yet decent quality option, I think it would be good to have this thread easily accessible.

Also, it contains a lot of good hints for using the Zoom that's not readily apparent from the manual, plus toward the end some more high-tech advice on recording in general, including some useful links to more technical material.
