Help with RPGmaker

Could someone tell me:

1/How can I make an event disappear permanently?
2/How to show a face next to the message box?

1. You can't make it disappear from the map entirely, but you can make it so nothing happens when you walk over it anymore with a switch.

I don't have RM2k anymore, but here's sort of how it would work:
Make an event with two pages.
Have the first page so it's triggered when the hero walks over it and have the graphic just be transparent and have the events something like this.
<> Message "This is an example of a switch."
<> Change Switch "switch" On

You'll have to make a new switch called "switch", and turn it on. Then on the second page, on the left part of the event, click the even for Switch and select the switch you made. It won't remove it from the map, but it will keep it from activating.

I haven't used RM2k in a while, so that code may be a bit off, so do some investigating.

2. There's a button that says "Set character face" or something like that on the even action page. You have to use that command every time you want to change the face that's used in the text box.

Thanks.
