In terms of claiming challenges, I'm just letting this be known: There's a reason that this is called a Fuh-Q-Fest, which I'm sure you all know *g*, and so there's a few challenges in there that have had the label "[smut]" added to the end of them. This means that if you are considering claiming those challenges then you have to be willing to write R or NC-17 for them. There are also a few in there (mainly ones suggested by florahart ;P) that don't have the label applied, but it is generally assumed. This doesn't mean that you cannot write PG fics for other ones, as many of the challenges work well with that rating, but if a challenge is leaning towards or is blatantly suggesting that this calls for smut, please do so. ^_^
