New, have recently been messing around doing runs in Leo's Fortune. The game is listed here, but only in the form of Any%. Was wondering if its ok to submit IL runs? Or does this need to be requested as an added selection?

The moderator of the game would have to add a separate section for you to submit ILs to, so I'd suggest contacting ItsNiklass (was just on yesterday) and asking him if he'd do that for you. Once he creates a place for that on the page, you'll be able to submit directly to that.
