>>There was no voting messages this year - just an announcement on the main page for the voting process and then the info about the winners on the main page as well.

>>Wow, I'm so scared now - I don't know which preposition to use before "the main page" - would it be "on", "in" or "at"?

>"on"

as to the other message ("in school" or "at school") don't worry about it. While not correct, it is common to say "while in school" instead of "while at school." You probably just heard it said that way so many times that it sounded correct :o)
