Not really, or at least not on purpose (it's possible I've done things that count as exploits without really realising, but I can't think of anything). I read about the resto loop, but I've a feeling SkyRe does away with it (doesn't it involve using potions of enchanting or something? None of those in SkyRe...) and I'm not sufficiently intrigued by the possibilities to remove SkyRe from my game. I had one character nab stuff from the invisible chest in Dawnstar, but it totally unbalanced my game and I've a feeling one of my mods (probably the USKPs) makes it inaccessible anyway. I can't be bothered with things like stabbing Hadvar to level sneak. Not bothered if other people want to use these things, and I know the resto loop can be used rather creatively, I'm just not that interested in it myself.
