Where can I get more information on how mods work?
This one is easy. Check the amazing Oblivion Mod Faq by dev_akm for very detailed information on the nature of mod files, utilities designed to work with them and a lot of other very pertinent information that will save you much time in trying to figure out all sorts of questions related to using mods with your ES IV: Oblivion. If you have any questions, problems or concerns not answered in this FAQ, please feel free to post in the TES Oblivion Mod Forums and I will be able to address them.
