It does suck not being awake at 4am when plot is going on, but on the other hand when you get up in a morning there are tags in your inbox and new things to read, and who doesn't like that?! I've never had much of a problem with the time zone thing, although it can be a pain when you're getting into a tagging pattern and then you realise it's midnight and you need to get up in six hours.
I can safely say that you won't run short of lines. People are always up for throwing characters together here! And it's honestly one of the best games I've ever been in. Everyone's welcoming and grown up about things; rarely do we get much drama going on.
As for characters, we do need more mermaids! And if YOU make the bad egg, it means I don't have to. Because I've been eyeing that too. And I've made two newb characters in the past two months, so I should probably give my brain a break.
