[Mattakil]

hmmm, what does KillTimer do here?

It should work something like this:

pawn Код:

//whatever to show the textdraws
SetTimerEx(WelcomeMessage, 5000, 0, i, playerid);

//somewhere else
forward WelcomeMessage(playerid);
public WelcomeMessage(playerid)
{
    //textdrawhide here
}

That should be all you need to make that work
