[Help] Questions about v83 private server

[deathdevour]

1.Is there a way to remove the Maple Tips that keep on popping up in your chat randomly?

2.How can I make an MSI in game ? I dont want to make an MSI through editing wz files, and I thought it'd be a lot easier if i used !msi <itemID> <stats>

3. How would I remove the PIC after i double click on my character?

4. How would I make buffs last forever? Other servers have it and I dont .Btw I'm using MoopleDEV

5. When I log into my private server ( I am an admin), the hide skill is active ( character is transparent). There is no hide skill icon on the top right hand corner so I was wondering if there was a way to turn it off? Toggle On/Off? Somewhere in log in handler java files?

6.My EXP_RATES are retarded...I set it to 5 in the ServerConstants.java but it doesnt 5x the exp in game? I use the gm command !exprate 300, and it doesnt set the rate to 300. Help?

public class ServerConstants {
    public static short VERSION = 83;
