I don't think it'll go down. We might lose a bit of work and progress, but it won't die.You guys really think that FA will have to start all over? So we lose all our watchers, submissions and all the hard work we did? You really truely believe FA can afford that kind of downfall??
But let's say, for the sake of what you're asking, it does have to start again. I still don't think it'll die completely. Even if it takes a year to come back to life, people will flock back. There's the idea of "brand recognition", where something is associated with an concept or object. Even though Oreos weren't the original sandwich cookie, when we think of them, it's Oreos. FA has been around for a really long time, despite its glaring issues and how many times this kind of thing has happened, people come back.
Honest question though, since I've only recently come back to FA, this is the longest I've seen it down. Is this amount of time normal or...?
