There are two files for servant of the dawn one servant of the dawn and one servant of the dawn for SI, do i need the SI one if i have shivering isles installed then?

btw on some threads what does relz mean?

If you having Shivering Isles installed and activated, then you would use the .esp that says it's for SI, yes. And "relz" is more or less shorthand for "release," IE, a mod that's been released to the public. (Vs. a WIP, or work in progress.)

i don't mean esp file i mean't actual file to download as ones for SI and ones normal one but i thought its just in oblivion not SI as well?

also whats the script for the spoiler tag so you can just push a button?

Right...forgot that SotD offers two separate downloads. Anyway, what I said still stands: if you have Shivering Isles running, download the version that says "for SI." SotD doesn't extend its story into the Shivering Isles, but if you're running SI, you need the SI version of SotD for compatibility reasons, IIRC.

As for spoiler tags:

 Just use: [spoiler] spoileriffic text goes here [/spoiler]

ok thanks sorry i wasn't making myself to clear, but thanks for your help!
