I submitted a custom sheet for a non-ICE game to RPGSheets.com on Monday. Today I clicked on their Forum link, which I cannot currently recall how I got to--anyway, both that link and a link labelled RPGShop take me to RPGShop.com. RPGShop's last update was apparently at the end of February. Which raises the question of how active RPGSheets is.
Upon further inspection, RPGSheets does have RM sheets, though as I am not as familiar with RM as I am with HARP I cannot tell which version the sheet is from.
