So I've been reading up about some of the places I'd be interested in exploring, like Hyjal, and even thinking about places like BWL and Naxx which as a non-raider I never got to see at all, but are reportedly interesting and impressive just to see.
Beyond that, I'd even like to check out places like UBRS fully and with impunity, so I'm interested in checking out one of these 3rd-party map viewers. Of course, checking out different models and items with a model viewer would also be fun. I remember someone posted the full Scarlet outfit here some time ago.
However, I'm wondering if they're safe to use as far as keyboard hooks/trojans and so forth go, and if so, which versions would be safe and recommended to use with the current build of WoW (and won't get me somehow banned by Blizz).
