i think the FAQ looks great, and i can't think of anything in particular missing or inaccurate. (in short, being new to iRiver/Linux ownership, i feel like it's answered all my questions.) why not put this FAQ right on the site ? i could HTMLify it in a few minutes. actually, the website could use a nav menu, too. in which the FAQ should figure prominently. maybe i could slightly redesign the site a tiny bit ? em.
