@Lugia, thanks for the heads up!
Everyone else, yes copy your favorite Lugia racks (and related posts?) before that stuff disappears. Totally agree with "while these were done for different individual users, they're still super-useful as studies on how successful basic builds are put together." I've copied 13 of my favorite Lugia builds / examples.
Do we happen to know, as Lugia deletes older racks, will those disappear from forum threads? There are a lot of useful threads with racks posted as examples + some discussion. I haven't been on the forum long enough to know if the in-thread rack graphics get deleted if the original rack poster makes a rack change or deletion.
