So as I understood. You mean a Player can create a quest and reward other players for doing it ? Sounds pretty awesome. I would call it "Job Board" or something like that. Maybe I'll take some of my free time and make it happen.
I liked the idea, I will make this for my server. If nobody post on five days after I finish mine, I share for you guys. But I think that until there, someone will post.
Ho okay I misread your update function
need to replace -3 by 3
set .@account_id,getcharid(3);
updatePoints( .@account_id,3 );
// dispbottom "Relogue para ter seu VIP ativado.";
