try something like this

PHP Code:

public OnPlayerConnect(playerid)
{
    SetSpawnInfo(playerid,0,0,0,0,0,45.0,0,0,0,0,0,0);
    SpawnPlayer(playerid);     
    TogglePlayerSpectating(playerid,true);
    //show the dialogs for register/login
    return 1;
} 


If you want more dialogs to appear after registering, do something like this

PHP Code:

public OnDialogResponse(playerid,response,listitem,inputtext)
{
    if(dialogid == REGISTER_DIALOG)
    {
        //register the players account with your system
        //Show them the age dialog
    }
    else if(dialogid == AGE_DIALOG)
    {
         //show them the gender dialog
    }
    else if(dialogid == GENDER_DIALOG)
    {
       //okay since the player has now registered set their and and gender lets stick them to their first spawn!
       TogglePlayerSpectating(playerid,false);
       SetSpawnInfo(playerid,team,skin,X,Y,Z,FacingAngle,Gun1,Ammo1,Gun2,Ammo2,Gun3,Ammo3);
       SpawnPlayer(playerid);
    }    
    else if(dialogid == login)
    {
         //if the pasword matches and they log in
       TogglePlayerSpectating(playerid,false);
       SetSpawnInfo(playerid,team,skin,X,Y,Z,FacingAngle,Gun1,Ammo1,Gun2,Ammo2,Gun3,Ammo3);
       SpawnPlayer(playerid);
    }
    return 1;
} 


Sorry if this isn't what you were asking but I am pretty sure this will help you.
