if i'm left with big questions after reading the info page, that's a bad sign. (questions about small details or my specific situation is a different thing, i expect to have those.) alternatively, if i have to read more than two pages (maybe 3 if i hit up rules but honestly when are rules not all the same) before i can start thinking on a character, that's also a bad sign. it means that either the mods can't organize their shit or their concept is way too complicated. you should be able to cover everything in setting and faq.

also, make sure everything is consistent (dates for apping/reserving, names of important npcs, info given on different pages). this also means that i don't want to be able to tell which mod answered a question on the FAQ (unless they're signed or something). a mod team that all talks differently just makes you seem sloppy and disorganized (probably because at least one of you will talk in a stupid and unprofessional way and while i realize this is a hobby, come on. recognize what people expect if you choose to be an organizer)

also a personal pet peeve, make sure that everything works on all site skins. lots of people use a dark skin, so when you code your text as black and don't code the background as white, a bunch of us can't read it without highlighting which is an annoyance and a turn-off because it's both unnecessary (why does your text need to be set to black instead of left as default? there's no coding reason for this) and so easily fixed. i've seen the reverse happen too.

as for graphics, i don't really care. make sure they're not obnoxiously ugly and make sure you're set to show entries in the site skin, but otherwise it's not necessarily going to put me off if you're using a default layout.
