you can get your LO from multiple sources. A small but useful program called BOSS (Better Oblivion Sorting Software) or OBMM (Oblivion Mod Manager - a must have!) or Wrye Bash
I highly recommend getting OBMM since many mods require you to have that, and the others around here will point you in the direction of Wrye and BOSS, but for now, just for LO and future mods yo umay install you HAVE to get OBMM, and not long after, I will recommend BOSS.
Once you get OBMM, open it (if installed correctly it will be in your Oblivion folder), select Import/Export (th elast button on the bottom right of the screen), select "view Load Order", once the dialogue menu opens up, hit Cntrl + A (do not hit the plus sign, I mean, hit control and A) to highlight it all, then Cntrl + C to copy.
If you have a ton of mods in your list, when putting your LO in a response first type
