I don't think you should shut down server.
Don't worry, as long as there are any community supporting it (like Taiwanese community now) I won't shut it down.
Even if you are no longer interested in TOP, i believe that it can run off donations
Well, I don't believe it, because during time 6 months I was accepting donations, only 1 person decided to donate. Reason why it was closed is because it didn't work.
If people want to donate, they can declare so in this thread (like you did), so when I see at least few people interested then I will open donations again. I Hope that this make some sense.
